Slow-growing pedunculated nodule.

There have been limited reported cases of pedunculated basal cell carcinoma(BCC). Our case is original, and it combines two rare aspects of CBC: Pedunculated and giant. This uncommon aspect is rarely encountered.

A 94‐year‐old patient with no medical history presented with a tumor of the nose that had progressed for 3 years. On examination, he was phototype II. There was an exophytic tumor, ulcerated in the center of size 7 cm and located on the right nostril wing (Figure 1). Surgical excision the lesion was performed. A pedunculated giant basal cell carcinoma (BCC) was diagnosed with the large basaloid tumor cell with peripheral palisading and retraction artifact and dilated vascular spaces on histopathology. (Figure 2).

Pedunculated basal cell carcinoma (BCC) is a rare entity. It is characterized by a polypoid appearance and a pedicle, which attaches it to the skin. Histologically, it is also distinguished by a pedunculated exophytic appearance and by restriction of tumor aggregations to the polypoid area. On the contrary, giant BCC (GBCC) accounts for 1% of all BCCs. GBCC is characterized by a size greater than 5 cm and an aggressive histological profile. It occurs most often in the cephalic extremity.

Our case is original, and it combines two rare aspects of CBC: Pedunculated and giant. This uncommon aspect is rarely encountered.
