A trichoblastoma is a benign adnexal neoplasm composed of follicular germinative cells. It most commonly presents as a solitary nodule on the scalp, face, or perineum and occurs equally in males and females. It is diagnosed most commonly between the fourth and the sixth decades, and it is extremely rare in childhood. To our knowledge there is no prior case report of a primary trichoblastoma occurring outside the setting of a nevus sebaceous of Jadassohn in a child before adolescence. Herein we report a case of trichoblastoma of the right cheek in an 11-year-old Korean girl.

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.

Trichogerminoma (TG) is a rare, benign, cutaneous adnexal tumor originating from the hair germ epithelium. It typically presents as an asymptomatic, slowly enlarging nodule predominantly on the head, face, or trunk. Despite its benign nature, precise diagnosis is crucial because of its potential to become malignant.

Trichoblastic carcinoma, trichoblastoma, trichoepithelioma, and basal cell carcinoma are histologically characterised by basaloid cell proliferation. In this report, we describe the case of a 76-year-old man who presented with trichoblastic carcinoma admixed with histological features of trichoblastoma, trichoepithelioma, and basal cell carcinoma. These tumours may not be situated separately but must be related to each other in terms of tumorigenesis.
