Sigmoid Squamous Cell Carcinoma presenting as a bladder mass: A case report

@#Primary squamous cell carcinoma (SCC) of the colon and rectum is a rare malignancy, with an incidence of less than 1 in 1,000 diagnosed colorectal cancers. This is a case of a 59-year-old male who presented with a three-month history of urinary symptoms. Work-up, however, revealed a locally-advanced, partially-obstructing primary sigmoid squamous cell carcinoma with extension to the urinary bladder. He subsequently underwent a proximal bowel diversion after extensive carcinomatosis was discovered on diagnostic laparoscopy. Colon SCC represents less than 0.5% of all colorectal tumors, and its incidence is estimated to be 0.1%. Clinically, it presents with similar signs and symptoms as colorectal adenocarcinoma. No standardized management approach has been established yet. A multidisciplinary team approach is essential in dealing with such cases. Keen attention and further investigation are warranted to clearly define the management approach to achieve better outcomes.

Platelet-rich plasma injection of skin graft in a patient with squamous cell carcinoma and psoriasis on prolonged methotrexate therapy: A case report

Introduction@#Psoriasis and some of its treatments such as methotrexate have been linked to the development of non-melanoma skin cancers including cutaneous squamous cell carcinoma (SCC). Chronic maque psoriasis, Koebnerization, and prolonged methotrexate therapy are some of the concerns that may impact wound healing and graft uptake when treating these patients. @*Case Report@#We report a case of a 64-year-old male with a 32-year history of moderate to severe psoriasis continuously self-medicating with methotrexate for 30 years who presented with a solitary indurated tumor with ulceration on the right anterior leg. Histopathology result revealed acantholytic cSCC. The patient concomitantly has generalized psoriatic plaques that complicated the selection of donor site for the skin graft, and raised concerns on wound healing and graft uptake. He underwent wide excision surgery with gastrocnemius (medial head) flap and split thickness skin graft. Platelet-rich plasma (PRP) injections were utilized post-operatively to increase graft survival and donor site regeneration. @*Discussion@#The main risk factors for the development of cSCC for this patient are the history of chronic plaque psoriasis and chronic methotrexate therapy. These two can also complicate the success of grafting and wound healing for this patient. PRP was utilized to for better graft survival, faster wound healing, and prevention of Koebnerization.

Erythroderma as first manifestation of squamous cell lung cancer: rare case report

Abstract Erythroderma as the first manifestation of a solid organ malignancy is rare. The underlying cancer is a challenging condition to diagnose. There are a few cases of erythroderma in cancer patients reported in the literature. We here describe the case of a 70-year-old man who presented with asthenia, weight loss, dry cough and total body erythema with desquamation over the past month. A chest computed tomography scan showed a nodular lesion, which was finally diagnosed as a squamous cell lung carcinoma. To our knowledge, as an erythroderma presentation, only 13 cases have been reported in the literature. This case report demonstrates the need to search for a neoplasm in patients presenting with erythroderma, particularly in the presence of accompanying debilitating symptoms.

Retalho de peitoral maior estendido e pediculado para reconstrução de região orbito-fronto-parietal direita após exérese de carcinoma espinocelular invasivo / Extended and pedicled pectoralis major flap for right orbitofrontal-parietal reconstruction following invasive squamous cell carcinoma resection

Introdução: O retalho miocutâneo de peitoral maior é um dos mais usados na reconstrução de defeitos da cabeça e pescoço, porém com restrição ao terço médio da face. Com técnicas de dissecção de perfurantes, consegue-se alongar mais o pedículo, obtendo coberturas da região orbito-fronto-parietal. Relato de Caso: Paciente masculino de 63 anos apresentando carcinoma espinocelular invasivo pouco diferenciado, que após sua ressecção cirúrgica apresentou defeito final de 12,0 x 18,0cm na região órbito-fronto-parietal direita com exposição de dura-máter, seio frontal e órbita superior direita. Foi desenhado retalho de peitoral maior com ilha cutânea de dimensões iguais ao defeito na região paraesternal direita, desde o quarto espaço intercostal até a região subcostal (estendido). O pedículo foi seccionado após 4 semanas. A cobertura foi efetiva, sem complicações maiores e resultado estético satisfatório. Conclusão: Este retalho mostrou ser uma excelente opção para reconstrução do terço superior da cabeça quando existam limitações para a realização de microcirurgia.

Bimodal Chromoendoscopy with Confocal Laser Endomicroscopy for the Detection of Early Esophageal Squamous Cell Neoplasms

BACKGROUND/AIMS: This study aimed to evaluate the diagnostic accuracy of dual-focus narrow-band imaging (dNBI) and Lugol'schromoendoscopy (LCE) combined with probe-based confocal laser endomicroscopy (pCLE) to screen for esophageal squamous cell neoplasms (ESCNs) in patients with a history of head and neck cancer. METHODS: From March to August 2016, dNBI was performed. Next, LCE was performed, followed by pCLE and biopsy. Histology has historically been the gold standard to diagnose ESCN. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of dNBI and LCE adjunct with pCLE were determined. RESULTS: Twenty-four patients were included. Ten ESCNs were found in 8 patients (33%). Forty percent of high-graded intraepithelial neoplasias and all low-grade intraepithelial neoplasias were overlooked by dNBI. The sensitivity, specificity, PPV, NPV, and accuracy of dNBI vs. LCE combined with pCLE were 50% vs. 80%, 62% vs. 67%, 36% vs. 44%, 75% vs. 91%, and 83% vs. 70%, respectively. CONCLUSIONS: The use of dNBI to detect ESCN was suboptimal. LCE with pCLE following dNBI had additional value for detecting esophageal dysplasia not detected by dNBI. The use of pCLE to detect dNBI-missed lesions yielded a high NPV, while pCLE-guided biopsy could reduce the number of unnecessary biopsies.

New Diagnostic Approach for Esophageal Squamous Cell Neoplasms Using Linked Color Imaging and Blue Laser Imaging Combined with Iodine Staining

A 62-year-old man with a flat early esophageal cancer was referred for endoscopic treatment. White light imaging revealed a pale red lesion, whereas linked color imaging (LCI) and blue laser imaging (BLI) yielded purple and brown images, respectively. Iodine staining demonstrated a large unstained area with a homogenous but very weak pink-color sign. This area appeared more clearly as purple and green on LCI and BLI, respectively; however, a different colored portion was observed at the 4 o'clock position inside the iodine-unstained area. Histopathology findings of the resected specimen revealed squamous intraepithelial neoplasia at the 4 o'clock position and an esophageal squamous cell carcinoma in the remaining iodine-unstained area. LCI and BLI combined with iodine staining produce characteristic images that overcomes the pink-color sign, reflecting the histological features of a flat esophageal neoplasm. This new method is useful for detailed evaluation of early flat squamous cell neoplasms.

A Case of Nivolumab-induced Cutaneous Toxicity / 대한피부과학회지

Nivolumab is anti-programmed death 1 (PD1) receptor antibody, which can be used in the treatment of metastatic squamous cell cancer. By blocking the PD1 receptors on T cells, it enhances T-cell response against cancer cells. A 69-year-old man, who works as a farmer, presented with erythematous lichenified plaques on sun-exposed areas, such as the face, the chest, and both the forearms. Before the hospital visit, he was receiving lung cancer treatment with paclitaxel and cisplatin, but there was no improvement. Subsequently, the regimen was changed into nivolumab, and PET-CT showed decreased in cancer size. However, skin rashes developed simultaneously. It is consistent with the results of a previous study in which cutaneous side effects developed in 42% of responders compared to 7% of non-responders. Herein, we report a case of nivolumab-induced cutaneous toxicity on sun-exposed areas based on the clinical findings, including the distribution of rashes, which were improved after decreasing the nivolumab dose with literature review.

Chemoradiotherapy for Esophageal Cancer

Esophageal cancer is a highly lethal malignancy. Squamous cell cancer (SCC) and adenocarcinoma are two major histologic types of esophageal cancer. The therapeutic approaches for both histologic types tend to be similar. Endoscopic therapy is considered in patients with Tis and T1a, and surgery alone is recommended in patients with T1N0 esophageal SCC or adenocarcinoma. Definitive chemoradiotherapy is a reasonable option for patients unable to withstand surgery. Esophagectomy is considered as the initial treatment for patients with clinical T2N0 esophageal SCC and those with adenocarcinoma with low lymph node metastasis risk. Combined modality therapy is recommended for patients with T3N0, T4aN0, and clinically node-positive thoracic esophageal cancer, regardless of histology. Definitive concurrent chemoradiotherapy is the most appropriate treatment approach for patients with esophageal SCC who are not surgical candidates. Definitive concurrent chemoradiotherapy is also considered for esophageal SCC patients who are potential surgical candidates with an endoscopically documented complete response after neoadjuvant chemoradiotherapy. For chemoradiotherapy non-responders, surgery is recommended for those who remain operable after chemoradiotherapy. Esophagectomy is also recommended for patients with esophageal adenocarcinoma after neoadjuvant chemoradiotherapy. Definitive concurrent chemoradiotherapy is preferred over surgery in patients with cervical esophageal cancer because its survival rate is similar to that of surgery and major morbidity can be avoided. Concurrent chemoradiotherapy rather than radiation therapy alone is recommended for patients who can tolerate this approach for non-metastatic, inoperable, or unresectable esophageal SCC or adenocarcinoma.

Oral squamous papilloma: a view under clinical, fluorescence and histopathological aspects / Papiloma escamoso oral: uma visão sob aspectos clínicos, de fluorescência e histopatológicos

ABSTRACT Oral squamous papilloma is a benign tumor whose pathogenesis has been associated with human papillomavirus infection. Thus, it is noteworthy that human papillomavirus infection is one of the risk factors associated with the development of cervical, anogenital, pharynx, larynx and oral cavity carcinomas. Oral squamous papilloma can affect any region of the oral cavity, and transmission of human papillomavirus can occur by direct contact, sexual intercourse or from mother to child during delivery. The diagnosis is clinical and histopathological, with surgical removal representing the treatment of choice. Recently, widefield optical fluorescence has been used as a complementary examination to the conventional clinical examination in the screening of oral pathological lesions and for the delimitation of surgical margins. We report a case of oral squamous papilloma with its clinical, histopathological features and, in addition, from the perspective of wide field optical fluorescence.

RESUMO O papiloma escamoso oral é um tumor benigno, cuja patogênese tem sido associada à infecção pelo papilomavírus humano. A infecção pelo papilomavírus humano é um dos fatores de risco associado ao desenvolvimento dos carcinomas cervicais, anogenitais, faríngeos, laríngeos e da cavidade oral. O papiloma escamoso oral pode acometer qualquer região da cavidade oral, e a transmissão do papilomavírus humano ocorre por contato direto, relação sexual ou de mãe para filho durante o parto. O diagnóstico é clínico e histopatológico, e a remoção cirúrgica representa o tratamento de escolha. Recentemente, a fluorescência óptica de campo amplo tem sido empregada como exame complementar ao exame clínico convencional, no rastreio de lesões patológicas orais e para delimitação de margens cirúrgicas. Relatamos um caso de papiloma escamoso oral com suas características clínicas e histopatológicas, sob a perspectiva da fluorescência óptica de campo amplo.
