Store-and-Forward Teledermatology for Assessing Skin Cancer in 2023: Literature Review

Background: The role of teledermatology for skin lesion assessment has been a recent development, particularly, since the COVID-19 pandemic has impacted the ability to assess patients in person. The growing number of studies relating to this area reflects the evolving interest. Objective: This literature review aims to analyze the available research on store-and-forward teledermatology for skin lesion assessment. Methods: MEDLINE was searched for papers from January 2010 to November 2021. Papers were searched for assessment of time management, effectiveness, and image quality. Results: The reported effectiveness of store-and-forward teledermatology for skin lesion assessment produces heterogeneous results likely due to significant procedure variations. Most studies show high accuracy and diagnostic concordance of teledermatology compared to in-person dermatologist assessment and histopathology. This is improved through the use of teledermoscopy. Most literature shows that teledermatology reduces time to advice and definitive treatment compared to outpatient clinic assessment. Conclusions: Overall, teledermatology offers a comparable standard of effectiveness to in-person assessment. It can save significant time in expediting advice and management. Image quality and inclusion of dermoscopy have a considerable bearing on the overall effectiveness. © Leah Kirsten Jones, Amanda Oakley.

The analysis of cathepsin L that mediates cellular SARS-CoV-2 infection leading to COVID-19 in head and neck squamous cell carcinoma.

The vulnerability of the oral cavity to SARS-CoV-2 infection is well-known, and cancer patients are at a higher risk of COVID-19, emphasizing the need to prioritize this patient population. Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant cancers associated with early metastasis and poor prognosis. It has been established that cancerous tissues express Cathepsin L (CTSL), a proteinase that regulates cancer progression and SARS-CoV-2 entry. Therefore, it is essential to evaluate the correlation between disease outcomes and CTSL expression in cancer tissues and predict the susceptibility of cancer patients to SARS-CoV-2. In this study, we used transcriptomic and genomic data to profile CTSL expression in HNSCC and developed a CTSL signature that could reflect the response of HNSCC patients to chemotherapy and immunotherapy. Additionally, we investigated the relationship between CTSL expression and immune cell infiltration and established CTSL as a potential carcinogenic factor for HNSCC patients. These findings could aid in understanding the mechanisms underlying the increased susceptibility of HNSCC patients to SARS-CoV-2 and contribute to the development of therapy for both HNSCC and COVID-19.

Lung Aspergillus niger infection after SARS-CoV2

A 64-year-old never-smoker man, with professional exposure, presented to Marius Nasta Pneumophtisiology Institute for fatigability to effort, in the context of severe SARS-COV2 infection one month previously. His medical history includes pulmonary tuberculosis (55 years ago) and newly diagnosed type II diabetes (261 mg/dL glycemia). The thoracic tomography computer in the immediate post-COVID period (Fig. 1A) revealed the presence of glass ground lesions and a 3 cm nodule with cystic degeneration in the upper left lobe. A gross examination of the specimen identified a condensation area of 2.5 cm diameter, brown-grey colored, with necrosis and central ulceration. Microscopic examination showed the presence of bronchiectasis with squamous metaplasia of the epithelium, which appears ulcerated;numerous calcium oxalate crystals with adjacent foreign body granulomatous reaction;endobronchial are present fibrinous and inflammatory debris, brown-black pigment, and septate, dichotomous branching hyphae, suggestive of Aspergillus spp. A periodic acid-Schiff stain was performed, identifying the fungal hyphae. The histopathological diagnosis was bronchiectasis supra-infected and colonized with fungal filaments (Aspergillus niger).

Esophageal Squamous Cell Carcinoma: An Unfavorable Complication of Achalasia

Introduction: Achalasia is a motility disorder of the esophagus characterized by impaired relaxation of the lower esophageal sphincter and loss of peristalsis in the distal esophagus. It is a rare condition with an annual incidence of 0.5-1.2 per 100,000 individuals. The etiology of primary achalasia is unknown, however secondary achalasia can be attributed to malignancy, infections or systemic diseases such as amyloidosis. An infrequent complication of achalasia is esophageal squamous cell carcinoma which has a prevalence of 26 in every 1,000 cases. We present a case of interval locoregionally advanced esophageal squamous cell carcinoma only 2 years after a normal upper endoscopy. Case Description/Methods: A 67-year-old female with known achalasia and previous pneumatic dilation in her 30s presented to our outpatient clinic in 2019 with complaints of worsening chronic dysphagia. EGD was performed which revealed a significantly dilated esophagus with candida esophagitis. Despite completing antifungal therapy, she continued to experience dysphagia to solids and liquids. Barium swallow demonstrated absent peristalsis with pooling of contrast within the esophagus. High-Resolution Manometry testing demonstrated absent peristalsis. She opted for surgical myotomy, however due to COVID restrictions, the procedure was delayed. Repeat EGD was performed in 2022 for pre-surgical evaluation and showed a large obstructing friable esophageal mass in the lower third of the esophagus. Pathology was consistent with invasive poorly differentiated squamous cell carcinoma. PET scan showed locoregional disease with FDG-avid esophageal and gastrohepatic node lesions. She was started on chemoradiation with Paclitaxel and Carboplatin (Figure). Discussion(s): The risk of esophageal squamous cell carcinoma in achalasia has significantly increased with incidence of approximately 1 in 300 patients. The presumed mechanism of malignancy in achalasia is poor emptying resulting in food stasis, bacterial overgrowth and inflammation leading to dysplasia and development of carcinoma. Given the relatively low incidence, there are currently no guidelines on routine endoscopic screening to assess for malignancy in patients with achalasia. Survival rates are poor as patients are often diagnosed at advanced stages. This case aims to illustrate the importance and need for interval screening in individuals with long standing achalasia to improve outcomes.

Quality of Life Assessment With European Organisation for Research and Treatment of Cancer Questionnaire (Head and Neck Module 43) and Its Clinicopathological Correlation Among Patients Treated for Oral Squamous Cell Carcinoma: An Exploratory Study.

Introduction Oral cancer has a great impact on quality of life (QOL). Many risk factors influence the overall QOL. Our study was performed to evaluate the QOL among patients with oral cancer and to correlate it with age, gender, tobacco usage, and clinicopathological details. Methods We have used the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-HN43) and the Quality of Life Questionnaires for Core 30 (QLQ-C30) among the patients diagnosed with oral cancer after reporting to our institution. The Gpower calculation based on differences between two independent means reported by Meera et al. had a total sample size of 28 with an actual power of 0.9616. Thirty-five patients were included in the present study. Ethical clearance for this study was obtained, and there were no gender or age limits for enrollment. The patient demographic details and case history with relevant treatment information were collected from the DIAS (Dental Information Archival Software) of Saveetha Dental College, Chennai. After obtaining informed consent from the patients, the EORTC QLQ-HN43 and QLQ-C30 questionnaires were given to them. It was used both in Tamil and English. Various domains such as pain, appearance, and oral function were documented. The findings were correlated with clinical and histopathological findings. The collected data were tabulated and statistically analyzed with IBM Statistical Package for the Social Sciences (SPSS) version 20 (IBM Corp., USA). The mean ± SD were calculated for continuous variables, and frequency with percentage was determined for categorical parameters. Results The study included both men (57%) and women (43%) in the age range of 30-70 years, with a mean age of 50 years. Study samples included tobacco users (82%) and non-tobacco users (18%). Out of the 35 patients, 15 patients had lesions involving the buccal mucosa (42%) and 10 involving the tongue (28%). Oral squamous cell carcinoma (OSCC) was the most common type of lesion, and it was mostly treated surgically with resection and excision (82%), or just excision (18%). Seventy percent of our patients underwent reconstruction, while primary closure was done in only 30% of cases. All of the patients underwent neck dissection, including supraomohyoid neck dissection (52%), modified radial neck dissection (40%), and radial neck dissection (8%). Histopathology revealed that 49% had well-differentiated squamous cell carcinoma, 23% had moderately differentiated squamous cell carcinoma, and 28% had poorly differentiated squamous cell carcinoma. Out of the 35 included cases, five patients had died (14%). The primary site was buccal mucosa in all five cases, and surprisingly, three patients also had recurrences post-surgery or post-radiotherapy. We observed that the average rating of overall health and overall QOL at the time of diagnosis was 5.4. After one year of follow-up, the average rating of overall health and overall QOL was found to be 3.4. Conclusion The administration of EORTC QLQ-HN43 was found to be efficacious in our study on patients with OSCC. We could identify baseline data regarding the QOL of our patients treated for OSCC. We have identified critical domains of oral function that need to be focused upon to improve the overall QOL of OSCC patients through adjunctive therapies. We have also identified higher mortality and overall poorer QOL in patients with OSCC involving the buccal mucosa.

The Impact of COVID-19 on Oral Cancer Diagnosis: A Systematic Review

The Coronavirus-19 pandemic has led to severe collapses in international health systems that have repercussions at all levels of disease prevention. Oral squamous cell carcinoma (OSCC) is the most common head / neck malignancy, and it is usually diagnosed late due to patients neglecting symptoms. The purpose of this systematic review is to verify the impact of Sars-Cov-2 pandemic on OSCC diagnosis. The search methodology follows the PRISMA statement performing a PubMed investigation from 2019 to 2021 using MeSH such as "Covid-19;oral cancer”. A multidisciplinary approach would be effective, with a broadening of the knowledge of health professionals to identify cancerous lesions. A timely diagnosis of OSCC is crucial and its management is fundamental also for dental specialists. With the aim to anticipate the diagnosis, it will be desirable to set prevention campaigns also by the assistance in telemedicine. © Pulcini, R., D'Agostino, S., Dolci, M., Bissioli, A., Caporaso, L., and Iarussi, F.

Early detection of recurrent HPV+ hypopharyngeal squamous cell carcinoma by circulating tumor DNA

Circulating tumor DNA is a liquid biomarker that offers a highly specific method to assess HPV-associated tumor burden via a blood draw. It has the potential for many clinical applications in cancer care, including prognostication, monitoring treatment response, and surveillance for disease recurrence. In this case report, we present a case of recurrent HPV-associated hypopharyngeal squamous cell carcinoma first detected by circulating tumor HPV DNA that demonstrates the role of circulating tumor HPV DNA tests in posttreatment surveillance and the utility of HPV testing in all HPV-mediated tumors, regardless of subsite.Copyright © 2023 Elsevier Inc.

Changes in demographic and smoking history trends in patients referred to a London thoracic malignancy specialist centre between 2010-2021: The Guy's Cancer Centre experience

Background In the UK it is estimated that 10-15% of lung cancer cases occur in never-smokers. This study demonstrates the changes of the demographic characteristics, including the smoking status, of all the patients referred to the thoracic malignancy unit at Guy's Cancer Centre, South East London, between 2010 and 2021. Methods We included patients with a documented ICD10 diagnosis of bronchus and lung malignancy who were referred to Guy's thoracic malignancy unit from 2010 until 2021. A total of 6861 patients with a diagnosis of lung cancer were identified. We collected baseline demographic and clinical characteristics, including smoking status and socio-economic status for all the patients. Descriptive statistics were utilised to highlight the dynamic changes over the years of the referred patients. Results The number of referrals per year remained overall stable from 2010 until 2019, with a decrease in the number of referrals in 2020 and 2021, most likely due to the COVID-19 pandemic. We observed a gradual increase in the percentage of never smokers among the lung cancer patients: 5%, 8%, 10% and 13% of the referred patients were never smokers in the years 2010, 2015, 2018 and 2021 respectively. Median age remained stable across the years (range 68-71 years). Male percentage was 56%, 55%, 53% and 53% in 2010, 2015, 2018 and 2021 respectively. From the patients that we had a documented ethnic background the proportion of White/Black/Asian/Other or Mixed ethnicity remained stable across the years with a median 87%, 7%, 3%, and 3% respectively. The most common histological diagnosis was adenocarcinoma, followed by squamous cell carcinoma and small cell lung carcinoma. Conclusions The proportion of never-smoking to smoking related lung cancer has gradually increased between 2010 and 2021. There was little variability in age, sex and ethnic background. Never-smoking lung cancer is a distinct biological entity, therefore, further research should focus on the understanding of the aetiology and the risk factors leading to the development of lung cancer, in the absence of a history of tobacco exposure.

Circulating tumor HPV DNA as an alternative method to determine HPV status in oropharyngeal squamous cell carcinoma.

Human Papilloma Virus (HPV) testing is mandatory for all newly diagnosed oropharyngeal squamous cell carcinoma (OPSCC) due to its importance for prognostication and aiding in treatment decision making. Fine needle aspiration (FNA) is a widely used and accepted diagnostic tool for OPSCC. Although FNA can accurately determine histological diagnosis, results are often indeterminate or lack insufficient samples for HPV testing. For samples with an indeterminant FNA, we propose an alternate method for determining HPV status using circulating tumor tissue modified HPV DNA (ctHPVDNA). We report three cases that confirmed HPV status using ctHPVDNA following an indeterminate FNA. If validated, this non-invasive assay could prevent the need for repeat FNAs or operative biopsies for the sole purpose of determining HPV status.

The effect of the SARS-CoV-2 pandemic on suspected cancer referrals at a regional head and neck unit

The novel coronavirus SARS-CoV-2, initially identified in late 2019 as a small case cluster, has rapidly become a global pandemic. Government restrictions, closure of primary care services, interruption of cancer screening programmes, and fear of contracting the virus have demonstrably led to a reduction in referrals for suspected cancer and delays to treatment across the United Kingdom. A retrospective analysis was carried out on suspected cancer referrals to the maxillofacial service at Aberdeen Royal Infirmary during the 12 months from March 2020, and compared with the 12 months prior. Suspected cancer referrals reduced by 38.6% (p < 0.001) during this period, with a reduction in the percentage referred by General Dental Practitioners. Further analysis shows a proportionate reduction in squamous cell carcinoma diagnoses, with other diagnoses remaining stable. Time from referral to first appointment, biopsy, and treatment showed no change. Stage at diagnosis and treatment modality was also unaffected. Assuming no change to the incidence of head and neck malignancies, over a third of new malignancies may have been undiagnosed during the 12 months from March 2020. Evidence for the impact of the pandemic is likely to become apparent as services return to pre-pandemic levels and these patients begin to present.Copyright © 2021 The Authors

Two-week wait skin cancer referrals to a paediatric dermatology clinic: a service evaluation

Skin cancer in children is rare. Data from the USA indicate that paediatric melanoma accounts for approximately 1% of melanomas and up to 5% of all childhood cancers, and its incidence is declining. Paediatric nonmelanoma skin cancer (NMSC) is also rare and often associated with genetic conditions or iatrogenic risk factors such as prolonged immunosuppression. In the UK, suspected cancers are referred from primary care via the '2-week wait' (2WW) pathway. National Institute for Health and Care Excellence guidance (NG12) provides criteria to guide recognition and referral, aimed at improving cancer outcomes through early detection and diagnosis. Melanoma and squamous cell carcinoma are diagnosed in approximately 6% of all 2WW skin cancer referrals;however, the vast majority of these are in adults. We evaluated all urgent paediatric dermatology referrals made via the 2WW skin cancer pathway over a 21- month period (August 2019-May 2021). In total, 172 referrals were made. Fifty-two per cent were female and mean age at time of referral was 10 years (range 2 months-17 years). The mean wait time from referral to clinical review was 9.9 days (range 1-28). Skin biopsy was arranged in 27 (15.6%) patients;nine (33.3%) of these biopsies were completed by paediatric dermatologists and 18 (66.6%) were referred to plastic surgery. There were no confirmed cases of skin cancer. Referrals were deemed inappropriate in 22% of cases. Of these, 15 (41%) were misdirected referrals and the remainder included nonlesional dermatology, including cutaneous infections (24%) and inflammatory conditions (22%). The histological diagnoses are outlined in the Table. As 2WW referrals rise, services must plan efficient and cost-effective pathways for the provision of care. Referral rates for any suspected cancer are disproportionately high in young people, including for melanoma. Signs of a 'changing mole' are less sensitive in a paediatric cohort where melanoma is more likely to present as an amelanotic or nodular lesion. Over a 21-month period, we did not identify a paediatric skin cancer among patients referred on a 2WW pathway. The service burden related to 'stopping the clock' and patient tracking is considerable and has not been formally costed. As we attempt recovery following the COVID-19 pandemic, we plan to introduce greater use of teledermatology triage to address this issue. (Table Presented).

Mourning and restoration

During the endless days of March and April 2020, New York City experienced more than 20,000 COVID-19 deaths and was considered the "epicenter" of a new global pandemic. Nursing homes witnessed the virus's contagion at staggering rates, with elderly and debilitated patients coming in by the dozens, gasping for breath, scared they would die and never see their loved ones again. Our hospital and our lives were quickly transformed. The author spent most of his clinical effort during those months running a new eight-bed hospice unit in our hospital. The author then presents the story of a hospice patient, a fifty-nine-year-old Black male-to-female transgender homeless woman. She had been diagnosed with an aggressive squamous cell carcinoma. She underwent chemotherapy, radiation therapy, and surgery, including a diverting colectomy, leaving her with a permanent ostomy. She had several other medical problems-chronic kidney disease, heart disease, diabetes, major depression, and chronic lymphedema. Taking care in her last days of life was agonizing. The possibility to have spent more time getting to know her. To explore her world and navigate the challenges of her health and condition together. This is the privilege of the doctor-patient relationship. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Silver nitrate-induced skin inflammation mimicking surgical infection

Silver has been in medicine for hundreds of years and has proven antimicrobial properties. It was widely used until the Second World War, when antibiotics emerged. Silver nitrate (SN) sticks (75% silver nitrate and 25% potassium nitrate) are currently employed as a topical haemostatic agent for various cutaneous surgical procedures. In the initial phase of the COVID-19 pandemic, faced with a limited supply of personal protective equipment, we used SN stick haemostasis for several skin surgical procedures (including excisions). COVID-19-related guidance from the Trust recommended the avoidance of electrocautery owing to the generation of surgical plume;hence, SN stick haemostasis seemed a pragmatic option. Four female patients with a mean age of 67 years (range 48-75) presented with swelling, erythema and pain at the surgical site within a week of the procedure. Three had ellipse excisions for suspected melanoma and squamous cell carcinomas, and one had a shave excision for possible seborrhoeic keratosis. Postsurgical wound infection was suspected, but repeated microbiological swabs did not grow any pathogens. All patients failed to respond to broad-spectrum oral antibiotics, even after two courses. The inflammatory changes took up to 4 weeks to settle, with topical corticosteroids used for wound healing. On contact with moisture, SN sticks deliver free silver ions that form an eschar as they bind to the tissue and occlude vessels. The longer the tip contacts the tissue, the greater the degree of the resultant caustic action. It is widely used in clinical practice, especially wound care (overgranulation, epibole and delayed healing). A 2020 review found an increased incidence of postoperative pain along with pigmentary changes in surgical wounds treated with SN sticks vs. aluminium chloride hexahydrate and ferric subsulfate. In skin surgery, SN is used to cauterize superficial wounds after curettage and shave excision. It does not generate aerosol and, in a pandemic setting, this particular feature can be valuable. However, the potential to cause aseptic skin inflammation that mimics postoperative infection is noteworthy. There are no evidence-based guidelines for its use in dermatology. We believe that the SN is an effective haemostatic agent but can induce significant tissue inflammation in some patients, particularly if it is used in excisions when the cauterized tissue is closed. If SN-induced haemostasis for excision was to be adopted in clinical practice, our experience suggests that larger studies and guidelines are recommended.

Metastatic Squamous Cell Carcinoma of Unknown Primary to the Right Ventriclea Rare Cause of Acute Heart Failure

Background Large autopsy studies have shown intracardiac metastases in 15% of patients with disseminated cancer. We present a rare case of metastatic squamous cell carcinoma (SCC) of the heart with unknown primary. Case 55-year-old female with DVT, COVID-19 infection and stage IV metastatic SCC of uncertain origin presented with progressive fatigue and dyspnea. She had occlusion of left interlobar pulmonary artery and new large right ventricle (RV) mass consistent with tumor and thrombus invasion. Systemic anticoagulation was initiated. Decision-making Echocardiography showed a large mass in RV measuring 5 cm x 2.5 cm and occupying most of the RV cavity. Though her RV systolic function was reduced, she was unlikely to benefit from surgical resection due to disseminated disease. Piecemeal removal of RV mass alleviated the obstructed RV outflow tract. Histopathology featured squamous cell carcinoma. She had symptom resolution within a week following procedure. The patient was discharged home with oral anticoagulant. On follow up, she had not experienced any worsening of symptoms and changes in RV mass size despite compliance with chemotherapy (carboplatin and paclitaxel) and anticoagulation. Conclusion Metastatic SCC with unknown primary is a rare cause of acute heart failure that highlights the interplay between clinical findings and multimodal cardiac diagnostic imaging. An individualized approach is required for patients, balancing both risks of surgical and percutaneous intervention. [Formula presented]Copyright © 2023 American College of Cardiology Foundation

Fiji albinism project: raising awareness and destigmatizing albinism in Fiji

In 2020, there were reports of people with albinism being branded as 'Corona' and 'COVID-19', using individuals as scapegoats and further ostracizing them from communities. People with albinism are vulnerable to human rights' violations and suffer with skin and eye health. Albinism is increasingly recognized in the Pacific Region, particularly in the Polynesian community in Fiji, Samoa, Vanuatu and Tuvalu. A register has been created for Fijians with albinism, with the objective of understanding the scale and health needs of the population. In 2014, The Fiji Albinism Project was established through charity funding in partnership with the Fiji Ministry of Health. The aim is to improve the quality of life of people living with albinism in Fiji. Proformas are completed by Fijians with albinism and their details are collated into an Excel spreadsheet, including name, gender, date of birth, ethnicity, contact details, address, nearest health centre, school, date of entry and additional comments. The database currently holds the details of 172 people with albinism (aged 9 months-77 years), with 161 self-reporting as iTaukei. There are 88 females and 82 males registered (two do not have gender documented). Sixty-four participants are < 18 years of age. Basal and squamous cell carcinomas have been seen among adults, with one incidence of clinical Bowen disease in a child. Similar numbers of people attended the national skin clinic in 2020 vs. nonpandemic times. However, uptake of outreach clinics was reduced and fewer people with albinism are collecting free sunscreen. Owing to the COVID-19 pandemic, the first virtual International Albinism Awareness Day was held in 2020, with participants from Fiji. In 2020, a 5-year National Strategic Plan for Dermatology, Leprosy and Albinism was submitted and reviewed by the Minister of Health and Permanent Secretary of Health in Fiji. The plan includes proposals for continued free sunscreen and formalizing of referral pathways to Tamavua Twomey Hospital and The Pacific Eye Institute. This incorporation of albinism care within the Ministry of Health and Ministry of Education provides a model for other pacific islands and developing countries to follow.

Melanized (dematiaceous) fungal infections simulating skin cancer in African organ transplant recipients

Fungi are the most frequent skin infections in organ transplant recipients (OTRs) and usually present as superficial mycoses. Deeper infections are much less common, potentially more serious and the incidence is higher in the first few months post-transplant. We report two African OTRs with deep fungal infections caused by dematiaceous (melanized, pigmented or black) fungi, who both presented with suspected skin malignancies. A 60-year-old Nigerian man developed a painful, ulcerated, amelanotic, bleeding nodule on his right fourth toe 2 months after renal transplantation. Clinical differential diagnoses included Kaposi sarcoma (KS), amelanotic acral melanoma and subungual squamous cell carcinoma (SCC). However, histology showed pseudoepitheliomatous hyperplasia, extensive mixed inflammation, multinucleated giant cells and pigmented septate hyphae with rounded 'budding' forms. Periodic acid-Schiff, Grocott and Masson-Fontana stains were positive, and Alcian blue stain was negative, consistent with infection by a dematiaceous fungus. Fungal 18S polymerase chain reaction (PCR) was positive and culture identified Nigrograna mackinnonii. Treatment with oral itraconazole was supervised virtually during the COVID-19 pandemic. After 6 months there was minimal response and he opted for amputation of the digit. A 61-year-old Nigerian man presented 2 months after renal transplantation with a 2-cm diameter nodule on his left thigh at the site of a previous burn. This failed to respond to antibiotics. Magnetic resonance imaging was suggestive of possible malignancy, but surgery was deferred because of the COVID-19 pandemic. Two months later the lesion was 5 cm in diameter and verrucous with an 8-cm sessile, purplish plaque on his right forearm. Atypical KS, lymphoma and chronic burns-associated SCC were all considered. However, histology from both lesions was similar to the first patient. Fungal culture and 18S PCR confirmed infection with the dematiaceous fungus Alternaria alternata. At his request, the right thigh lesion was excised. The lesion on his forearm has partially responded to 8 months of ongoing oral itraconazole. In our African OTR cohort, KS is more common than deep fungal infection. However, despite this suspicion of skin malignancy, both patients had phaeohyphomycoses caused by dematiaceous fungi. Characterized by the presence of melanin in their cell walls, > 130 species of these plant pathogens and soil saprophytes are implicated in human disease, particularly in immunocompromised individuals. Although localized skin diseases (phaeohyphomycoses, chromoblastomycosis and mycetoma) are the most common manifestations, rare disseminated, central nervous system and pulmonary infections may prove fatal. Although uncommon, deep fungal infection should be considered in atypical skin lesions in OTRs;histology, tissue culture and fungal PCR are critical to confirming this diagnosis.
