Henna Tattoo: From Cosmetic Purposes to Dermatological Reactions.

Introduction: Henna, commonly used as a hair dye, is also used for temporary tattoos. It is commonly mixed with para-phenylenediamine (PPD) to enhance color intensity, which may induce cutaneous sensitization. Aim: This study aimed to describe the clinicodemographic features of patients with dermatological reactions to henna tattoos. Materials and Methods: This cross-sectional study, included patients with dermatological reactions to henna tattoos. All the patients were subjected to entire medical history including clinicodemographic data and general and dermatological examinations. Results: This study included 17 female patients with a mean age of 26.88 ± 6.6 years. Of these 17 patients; 41.2% were suburban residents, 58.8% were housewives, 70.6% were married, and 47.1% were middle socioeconomic class and 53% had type IV Fitzpatrick skin. All used black color and commercial henna for cosmetic purposes, 41.2% used market henna, and 35.3% used coiffeur henna. Many (70.6%) had localized reactions with 23.5% presenting with reaction of hands, 64.7% had acute eczematous reactions, and all had a progressive course. The mean duration of the reaction was 6.76 ± 2.6 days. The mean latency time of the reaction was 2.7 ± 0.85 days. Conclusion: This study concluded that public awareness of possible cutaneous reactions to henna tattoos should be increased. The health authority legislation should control the use of black henna to minimize the consequences.

Epidemiological and clinicopathological analysis of basal cell carcinoma in Egyptian population: a 5-year retrospective multicenter study.

PURPOSE: Basal cell carcinoma (BCC) is the most diagnosed type of cancer accounting for 80% of all keratinocyte malignancies. However, the exact demographic properties and clinicopathological criteria for BCC in Egyptians are not clearly reported. Our aim is to report and analyze the epidemiological and clinicopathological features of BCC in Egyptians. METHODS: We retrospectively reviewed the medical records for patients diagnosed pathologically with BCC during the period from January 2017 to December 2021. Data were recruited from four dermatology centers with different geographical distributions. RESULTS: We registered 544 patients. Their age ranged between 22-91 years with a mean of 61.6 ± 13.2 years. Females showed younger age of onset. The mean duration of the tumor was 3.9 ± 3.8 years. The most common involved region was the head (79.4%), and about one third of patients (32.2%) had a giant lesion (> 5 cm). The most common clinical presentation was ulcerative lesions (44.9%). Pathologically, the nodular type represented the most common variant (50.4%). CONCLUSION: Our results proposed that the annual incidence of BCC is increasing among Egyptians. Ultraviolet radiation is considered a high-risk factor of BCC leading to a higher affection of the head region and more prevalence in men. This study also highlights some criteria of BCC in Egyptians such as the long duration of the tumor, the early onset in females, the higher percentage of giant types, and the predominance of nodular type. To our knowledge, this is the first report describing the characteristic features of BCC among Egyptians.

A case of resistant multiple plantar warts cured with combined autologous platelet-rich plasma injection and topical salicylic acid 30.

BACKGROUND: Plantar warts are common benign cutaneous lesions affecting the plantar aspects of the feet; they are caused by infection of the keratinocytes by the human papillomavirus (HPV). The effective treatment of plantar warts is still a therapeutic challenge. AIM: This study aimed to assess the possible clinical efficacy and safety of the combined intralesional autologous platelet-rich plasma (PRP) injection with local application of salicylic acid 30% solution in the treatment of multiple resistant plantar warts. METHOD: In the present case, a 54-year-old immunocompetent male patient presented with multiple, bilateral resistant plantar warts. RESULTS: A complete clearance of the plantar warts was observed after three sessions of intralesional autologous PRP injections with one-month interval, combined with twice-daily local application of salicylic acid 30% solution between sessions. No recurrence was recorded after a nine-month follow-up from the last session. There were no reported side effects during or after the sessions. CONCLUSION: The combined intralesional autologous PRP injection with topical salicylic acid is an effective, economic, and safe modality of treatment for multiple resistant plantar warts.

Clinical and Laboratory Characteristics of Elderly Patients with Pruritus.

INTRODUCTION: For elderly, pruritus is considered the most common complaint in outpatient clinic. Pruritus occurs in association with primary skin disorders and can also be caused by many diseases and drugs. The aim of the work was to study clinical and laboratory characteristics of elderly patients with pruritus in Sohag, Egypt. PATIENTS AND METHODS: A cross-sectional study was conducted on 225 patients aged ≥60 years of both sexes complaining of pruritus and 160 age- and sex-matched patient group complaining of non-pruritic dermatological diseases. CBC, ESR, renal function tests, serology for HBV and HCV and blood glucose levels were done routinely in all patients (both groups). Skin biopsy was done in some selected cases. RESULTS: The mean duration of pruritus was 4.23 ± 4.9 months and was generalized in 73.8% of cases with moderate severity in 35.1% with winter exacerbation in 20%. Dermatological causes of pruritus were detected in 54.2%, followed by systemic causes in 29.8%. Eczema was the most common skin cause of senile itching in 33.7%, while renal diseases were the most common systemic cause in 46.2%. CONCLUSION: Senile pruritus is a common problem in elderly. Early and proper management is mandatory to improve their quality of life.

Superficial cryotherapy using dimethyl ether and propane mixture versus microneedling in the treatment of alopecia areata: A prospective single-blinded randomized clinical trial.

To verify and compare the therapeutic efficacy and safety of superficial cryotherapy using dimethyl ether and propane (DMEP) mixture vs. microneedling in the treatment of mild scalp alopecia areata (AA). In a prospective randomized single-blinded clinical trial, 80 patients with clinically evident scalp mild AA were randomly assigned into two groups of 40 patients each. Group (1) was treated by superficial cryotherapy using DMEP in three freeze-thaw cycles of 5 s each. Group (2) was treated by microneedling. Both groups were treated every 2 weeks for 6 sessions and followed up for 3 months after the last session. Patients were assessed by photographic documentation, trichoscopic evaluation, severity of alopecia tool (SALT) score, and alopecia areata symptom impact scale (AASIS). An excellent response was achieved in 15 (37.5%) of group (1) compared with 14 (35%) of group (2) patients, while a good response was achieved in 23 (57.5%) of group (1) compared with 21 (52.5%) of group (1) patients, with a statistically insignificant difference. The mean SALT score change percentage was a statistically significantly higher in group (2) patients. The mean AASIS change percentage was higher in group (1) patients, but this was a statistically insignificant. In both groups, the mean numbers of trichoscopic signs of AA significantly decreased from baseline to the end of follow-up period. Both therapeutic modalities were well-tolerated, with no recurrence after the follow-up period. Both superficial cryotherapy using DMEP mixture, and microneedling are simple, effective, and safe therapeutic options for mild scalp AA, however, microneedling showed higher efficacy.

Possible clinical efficacy and tolerability of platelet-rich plasma in the treatment of patients with recalcitrant plane warts: The first clinical study.

BACKGROUND: Plane warts are prevalent cutaneous diseases, caused by different serotypes of human papillomavirus. AIMS: This study aimed to assess the possible clinical efficacy and tolerability of platelet-rich plasma (PRP) in the treatment of patients with multiple recalcitrant plane warts. METHODS: This prospective cohort clinical study was carried out on 25 patients with clinical and dermoscopic evident multiple recalcitrant plane warts. The patients were treated with autologous intralesional PRP injections every month until a complete clearance or for a maximum of two sessions. Then, patients were clinically evaluated one month after every session and after a six-month follow-up from the last injection. RESULTS: Of the included patients, 20 (80%) patients had facial plane warts, 3 (12%) patients had plane warts in the dorsum of hands, and 2 (8%) patients had plane warts in the dorsal aspect of feet. 60% of the patients have more than 100 plane warts, and all the patients had plane warts than 1 cm in size. The complete improvement was observed in 20% and 100% of the patients after the first and second sessions, respectively. No recurrence was detected after a six-month follow-up. No side effects were recorded after the treatment sessions. CONCLUSION: Intralesional injection of PRP could be potentially effective and well-tolerated immunotherapy for the treatment of multiple recalcitrant plane warts. Whatever, more studies are needed with a larger sample size and a longer period of follow-up. Also, randomized and controlled studies are required to evaluate its efficacy in treating different clinical types of warts.

Truncal Varicosities and Bilateral Port-wine Stain with Spinal Deformities Associated with Klippel-Trenaunay-Weber Syndrome.

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital disorder characterized by asymmetric limb hypertrophy, usually of the lower limbs, as well as vascular anomalies and capillary malformations under the skin, termed as port-wine stain. KTWS is prevalent in all parts of the world. It has a high degree of diversity of the associated malformations. In the present case, vascular/lymphatic malformations were evident by the presence of bilateral port-wine stain and lymphangioma. More interestingly, prominent aberrant veins (truncal varicosities) were found in the anterior chest wall, together with the presence of multiple angiolipomatosis. Bone deformities were more than limb hypertrophy and macrodactyly and extended to spinal deformities in the form of scoliotic changes.

Superficial Morphea: Clinicopathological Characteristics and a Novel Therapeutic Outcome to Excimer Light Therapy.

INTRODUCTION: Superficial morphea (SM) is an uncommon entity that was described in the literature without definitive correlation to localized scleroderma (LS) or other atrophoderma diseases. AIM: To demonstrate the clinicopathological features of SM and evaluate the efficacy of different therapeutic modalities in its management. PATIENTS AND METHODS: A total of 28 patients with SM were studied during the period from 2010 to 2015. Clinicopathological features and therapeutic outcomes were recorded and analyzed. RESULTS: Clinically, SM was predominant in females (71.4%) with an average onset at 33 years of age and an average duration of 15 months. It was commonly presented as asymptomatic, darkly pigmented, and multiple and slightly indurated patches. The lesions were mostly ill-defined, large-sized, and located more on the trunk. Histologically, thickening of collagen fibers was observed either localized to the papillary dermis only (38.9%) or extended into the upper reticular dermis (61.1%). Elastic fibers were generally diminished in the upper reticular dermis while the number of fibroblasts and basal melanin pigmentation were increased in the majority of cases (92.9% and 96.4%, respectively). The most commonly associated diseases were diabetes mellitus (50%) and hepatitis C virus (HCV) infection (42.8%), and their incidence was significantly higher than that in patients with LS. Excimer light showed promising effective results in the treatment of most cases (78.9%) while the response to other modalities such as topical corticosteroid alone or in combination with tacrolimus or treatment with UVA1 alone was less effective (7.1%, 23.1%, and 5%, respectively). CONCLUSION: Our results proposed that SM is a distinctive clinicopathological variant and not a stage in the spectrum of LS. The novel response of SM to excimer light and not for UVA1 therapy also suggests the different therapeutic outcome of SM from LS. Although SM has a significant association with DM and HCV infection, they seem not to affect the course of the disease.

Clinicopathologic, immunophenotyping and cytogenetic analysis of Sweet syndrome in Egyptian patients with acute myeloid leukemia.

BACKGROUND: Sweet syndrome (SS) is an uncommon dermatologic disorder that could be associated with hematologic malignancies. OBJECTIVE: To describe the clinicopathologic, immunophenotyping and cytogenetic characteristics of SS in Egyptian patients with acute myeloid leukemia (AML). METHODS: The study was conducted during the period from April 2011 to March 2015. For each patient, a clinical evaluation and histological assessment of cutaneous lesions were recorded. Diagnostic investigations, immunophenotyping and cytogenetic features of leukemia were analyzed. Therapeutic monitoring and follow up of both diseases were registered. RESULTS: The study included 13 patients (7 males and 6 females) with a mean age of 44.4±17.49years. Fever was recorded in 10 cases and most of the lesions (61.5%) appeared during the post remission period. Clinically, the lesions were more frequently located on the extremities (61.5%), presented as solitary lesion (53.8%) and mostly tender (69.2%). Atypical presentations were observed in 5 cases and included ulcerative lesion, indurated mass and a gangrenous mass. Histological assessment revealed two patterns of inflammatory reactions described as classic (dermal) form (38.5%) and deep (subcutaneous) form (61.5%). Laboratory investigations showed leukocytosis in 61.5%, neutropenia in 38.5%, anaemia in 92.3%, and thrombocytopenia in 84.6%. Bone marrow aspiration and biopsy showed suppressed trilineage hematopoesis in 84.6% and blast cell count >50% in 69.2%. The common subtypes of AML included M2 and M4 (23.1% for each). Cytogenetic studies revealed genetic abnormalities in 69.2% of cases. Most of the cases (76.9%) showed a poor response to oral prednisolone but responded well to alternative therapies, including dapsone, colchicine and cyclosporine. CONCLUSION: Sweet syndrome associated with AML may show atypical clinical forms that have an aggressive course and is mostly associated with subcutaneous involvement. Although chemotherapy of AML may play a significant role in the development of SS, the exact mechanism remains unclear. The disease is considered a steroid refractory and genetic abnormalities may have a role in altering the classic nature of the disease.

Cutaneous Granulomas Associated With Interferon Therapy.

Treatment with interferon (IFN) could be associated with variable cutaneous adverse reactions. The aim of this study was to describe the clinicopathological spectrum of cutaneous granulomas associated with IFN therapy and identify the causal relation between IFN therapy and granulomatous reactions. The study included 18 patients (16 males and 2 females) with an average age of 48 years. Clinically, most of the lesions were solitary (83.3%) and located on the face (44.4%) and/or trunk (38.9%). The lesions were commonly presented as nodules (33.3%) or plaques (27.8%) with a common size of 5-10 cm. Granulomatous reactions were localized to the injection site in 4 cases, distributed on other body areas (remote granuloma) in 11 cases, and associated with lung involvement (systemic granuloma) in 3 cases. Histologically, injection site granuloma showed suppurative reaction in 75% and sarcoidal reaction in 25%. Remote granuloma showed tuberculoid reaction in 27.3%, interstitial in 27.3%, and sarcoidal in 45.4%. Systemic granuloma showed sarcoidal reaction in all cases. After withdrawal of IFN, only 3 lesions showed spontaneous complete clearance, whereas most of the lesions (83.3%) showed only partial improvement. Our results suggested that IFN is not a causal agent of all associated cutaneous granulomas but it mostly provokes the appearance of granulomatous reactions in susceptible individuals. Findings that prove this concept include the formation of granuloma in body sites away from the injection site, the heterogeneous pattern of granuloma both clinically and histologically, and incomplete clearance of most of the lesions after withdrawal of IFN.
