Immunohistochemical findings and differential diagnosis of papillary-type cutaneous verrucous carcinoma of the neck: A case report

A Case of Huge Cutaneous Verrucous Carcinoma of the Neck

Verrucous carcinoma (VC) is a rare subtype of squamous cell carcinoma. VC commonly occurs in the mucosa, but rarely occurs in the skin. The treatment for VC is surgical removal of the tumor. Because lymph node metastasis of VC is rare, the indications for prophylactic neck dissection for cutaneous VC of the neck are controversial. Here, we present the case of a 68-year-old man with a huge cutaneous VC of the neck and the long-term clinical course. The tumor occupied the entire right cervical skin, with suspected lymph node metastasis in the affected neck. Tumor resection and neck lymph node dissection were performed. Pathological examination revealed cutaneous VC with invasion to the adjacent tissues and no lymph node metastasis. Cutaneous VC of the neck is likely to grow locally without regional lymph node metastasis regardless of the long-term course and the size of the tumor.

Squamous Cell Carcinoma Arising within Verruca Vulgaris on the Nipple

Cutaneous squamous cell carcinoma (SCC) is a common form of skin cancer and often appears as a hard, scaly lump that occasionally ulcerates. It is usually associated with cumulative exposure to ultraviolet light, although prior scarring, chronic wounds, exposure to radiation, HPV infection, and immunosuppression are also associated risk factors. Primary SCC of the nipple is very rare and only a few cases have been reported. We present a case of a 49-year-old female with concerns of a right nipple lesion with erythema and pain. She was initially evaluated for Paget's disease with an underlying malignancy and cellulitis, but, after biopsy and investigation, she was found to have a well-differentiated SCC arising from a verruca vulgaris. Current literature does not provide distinct guidelines on management of SCC or its variants on the nipple, and the case was managed based off of SCC at other cutaneous sites as well as other cases of SCC on the nipple.
