Squamous cell carcinoma is a morphologically heterogenous neoplasm of specific histologic entities involved in human papillomavirus infection. The condylomatous types of squamous cell vulvar carcinoma, caused by HPV-16, most often manifest as exophytic papillary tumors mimicking condylomas.

Basal cell carcinoma (BCC) is the most common non-melanoma type of skin cancer described in humans that originates in the epidermis, more specifically in the basal layer and its appendages. Environmental, genetic and phenotypic factors contribute to the onset of this cancer; however, damage caused by ultraviolet radiation from sunlight is the primary risk factor. The emergence of this neoplasm in unexposed body areas, such as the soles, groin, armpit, scrotum or vulva is very rare.

Basal cell carcinomas (BCC) are driven primarily by cumulative ultraviolet (UV) radiation exposure resulting in activation of the Hedgehog (Hh) signaling pathway, often as a result of UV-mediated Patched-1 (PTCH1) gene inactivation. Accordingly, BCCs most commonly arise at sun-exposed sites such as the head and neck. Very rarely, BCCs can arise at sun-protected sites such as the genital skin and perianal area.

Cystic basal cell carcinoma (BCC) is a rare subtype of BCC (1). Histologically, it is usually characterized by multiple small cysts without a clinical cystic appearance (2). Herein, we report an unusual case of cystic BCC with a large vulvar cyst.

: Vulvar epidermolytic hyperkeratosis (EHK) is an exceedingly rare dermatological condition, often presenting as solitary or multiple lesions in the vulvar region. Due to its clinical resemblance to other vulvar disorders, such as condyloma acuminatum, Bowenoid papulosis, and squamous cell carcinoma, vulvar EHK poses significant diagnostic challenges. While individual case reports and small case series have documented instances of vulvar EHK, comprehensive studies systematically consolidating the clinical, histopathological, and therapeutic aspects of this condition remain lacking.
