Giant basal cell carcinoma (GBCC) is a rare skin cancer characterized by an aggressive biological behavior with extensive local invasion, frequent metastasis, and associated poor prognosis. Wide local excision with sentinel lymph node biopsy is often warranted for this condition, and reconstruction by local rotational flap is one of the best surgical techniques for repairing similar skin cancers with a relatively large skin defect. A 59-year-old man who was a former construction worker with a significant smoking history presented with a single giant suspicious chronic ulcerating skin lesion measuring 9 x 7 cm that proved to be a basal cell carcinoma (BCC) on his left shoulder. The patient was negative for enlarged or palpable lymph nodes and underwent a wide local excision and primary repair with a local flap. Despite negative margins, his follow-up visits at six, nine, and 10 months revealed numerous suspicious lesions that further required multiple local wide excisions that showed new basal cell carcinoma and recurrence to the left axilla. Given the invasiveness of his skin cancer, he was referred to oncology and later treated by chemoradiation. Patients with multiple risk factors are associated with a higher incidence of more invasive skin cancer due to possible cumulative effects. The therapeutic approach for GBCC should involve multidisciplinary teams, with wide local resection of the tumor with possible sentinel lymph node biopsy, local rotational flap for reconstruction of the wide defect, and adjuvant chemoradiotherapy if necessary.
Chronic lymphedema (CL) due to failure of lymphatic drainage harbors an immunologically vulnerable environment for the development of various neoplasms. Independently, either melanoma or basal cell carcinoma (BCC) arising from CL has only been reported, but synchronous melanoma and BCC originating from CL is never reported. We report a very rare case of synchronous melanoma and BCC arising from the lymphedematous upper extremity developed secondary to axillary lymphadenectomy for breast cancer. Additionally, a literature review reporting either melanoma or BCC in the lymphedematous area was performed using Medline and PubMed databases.
Metastatic cutaneous lesions from colorectal in origin are extremely rare, and especially without any visceral metastasis. Due to its poor response to chemotherapy, it is a poor prognostic indicator with a 1–6 month(s) death rate. Routine screening colonoscopy should be highly encouraged. This case is about a patient with obstructing, bleeding right colon mass and metastatic cutaneous soft tissue mass postcolonic mass resection. The biology and the mechanism of these metastatic lesions are not well understood, and they can be mistaken with any other primary soft tissue malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
