Basal cell carcinoma (BCC) is the most common skin cancer. It generally has an indolent course with low rates of metastasis and mortality. However, BCC is locally invasive and can cause significant morbidity due to destructive local spread. We report our experience with a patient who was referred to our skin cancer unit due to a previously neglected lesion on the parietal region of the scalp, which had developed for 7 years. The patient was prescribed vismodegib on the basis that surgery could cause excessive functional and aesthetic damage. The patient had an objective partial response after 20 months of treatment. He was then submitted to radical skin excision, leaving a large defect that was reconstructed using a free latissimus dorsi muscle flap. The patient recovered well, and at the 1-year follow-up there were no signs of local recurrence.Our case demonstrates the value of vismodegib treatment prior to surgery in a locally advanced, high-risk scalp BCC and highlights the importance of an individualized and specialized approach with these patients, within a multidisciplinary team.

Malignant melanoma (MM) arising primarily in the cervix is exceedingly rare and has a poor prognosis. We report the case of a primary MM of the cervix in a 64-year-old woman with vaginal bleeding. She presented with a cervical amelanotic lesion which on biopsy rendered the diagnosis of MM. The patient was staged as International Federation of Gynecology and Obstetrics IIB and underwent Wertheim-Meigshysterectomy followed by brachytherapy. One year later, she was diagnosed with a large pelvic relapse for which surgery was performed. She then presented with a vaginal relapse and an isolated hepatic lesion, both of which were proposed for surgery. The diagnosis of MM of the cervix is a clinical and pathological challenge due to its rarity and overlapping features. Cytology cannot accurately diagnose it. Moreover, amelanotic MMs must be distinguished from other poorly differentiated carcinomas by diagnosis that ultimately relies on immunohistochemical staining. Radical surgery is the only treatment showing predictive benefit.

Eccrine hidradenocarcinoma is a rare adnexal neoplasm arising from the eccrine sweat glands of the skin. Surgery and radiotherapy are the mainstay of treatment, and chemotherapy is reserved for unresectable or metastatic lesions. We present the case of a 60-year-old man, referred for treatment of an unresectable basal cell carcinoma of the scalp. He started Vismodegib in January of 2017 but progressed after three months. A new biopsy showed a poorly differentiated carcinoma. The patient started carboplatin/paclitaxel with a major response, enabling surgery in December of 2017. Pathology concluded on a hidradenocarcinoma, R1, and radiotherapy was not possible due to local infection. Four months later, he underwent radiotherapy due to local recurrence, and restarted carboplatin/paclitaxel, but with progressive disease. An exploratory surgery in October of 2018 revealed unresectable disease. Restaging showed lung metastasis and second-line chemotherapy was proposed. However, due to continued clinical deterioration, the patient died in February of 2019.
