Blue nevus is a congenital and acquired melanocytic proliferation that includes different histological types. The atypical cellular type has been rarely described and it classically has a benign course. However, because of its intermediate features between common blue nevus and malignant blue nevus, long-term clinical follow-up is required. Here we report the case of a 28-year-old woman who presented with an atypical cellular blue nevus on the right foot.
ABSTRACT
Cutaneous squamous cell carcinoma (SCC) exhibiting microcystic adnexal carcinoma-like differentiation is an extremely rare tumor that shows both squamous and ductal differentiation. This tumor is often misdiagnosed clinically and histologically and is confused with other malignant and benign cutaneous neoplasms. It usually occurs in middle-aged to older adults. Here, we report a case of SCC with microcystic adnexal carcinoma-like differentiation on the left chin of a 71-year-old male. The histopathological examination revealed a nodular tumor infiltrating the dermis, subcutaneous fat, and striated muscle tissue, consisting of both prominent atypical squamous differentiation and foci of duct-like structures.
