An Interesting Coexistence of a Classical-Nodular and an Adenoid-Ulcerous Basal Cell Carcinoma in the Same Anatomic Location

Abstract

Basal cell carcinoma is the most frequent malignant tumor of the skin, and the most common carcinoma found in some countries. The main clinical subtypes of BCC are nodular, superficial, pigmented and morpheaform. The majority of the lesions appear on the head and neck, with a particular predilection on the upper central part of the face. Here we report a 62 year-old woman with two different morphological types of BCC which developed in the same area. The tumors have developed two months apart on the right paranasal region in close proximity. With the clinical examination and histopathological examination of punch biopsy specimens, the diagnoses of the lesions were confirmed as a nodular and an adenoid BCC. The tumors were totally removed with surgical excision. Neither recurrence nor new lesion was observed on the lesional or near areas in a 24-month follow-up period. To the best of our knowledge the presence of the two different morphological types of BCC in the same anatomical location has not been reported previously.
