Giant epidermal cyst with intramuscular extension: a rare occurrence

2015

An epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. When its size is greater than 5 cm, it is recognised as a giant epidermal cyst. A subcutaneous giant epidermal cyst with intramuscular extension is extremely rare. The authors report a case of a 74-year-old man who presented with a painless, slow-growing left gluteal mass of 6-month duration. Examination revealed a large left gluteal mass that was fixed to the underlying structures. A small epidermal cyst with visible punctum was noted at the medial aspect of the mass. MRI demonstrated a large, lobulated left gluteal lesion measuring 20 cm×16 cm×10 cm. The lesion was partly within the gluteal maximus muscle and partly within the subcutaneous tissue. MRI and ultrasound features of the lesion were consistent with a giant epidermal cyst with intramuscular extension. The lesion was excised and histology confirmed the diagnosis.

“…Thereby, epidermoid cysts which are more than 5 cm in size are termed as “giant epidermoid cysts.” Giant epidermoid cysts are comparatively rare especially in the head and neck area. [ 5 9 ] The size of the cyst is of significance as giant cysts (>5 cm) have more chances of malignant transformation as compared to conventional cysts. The present case is a case of giant epidermoid/keratinous cyst.…”

Congenital giant keratinous cyst mimicking lipoma: Case report and review

et al. 2015

Epidermal cysts represent the most common cutaneous cysts. They arise following a localized inflammation of the hair follicle and occasionally after the implantation of the epithelium, following a trauma or surgery. Conventional epidermal cysts are about 5 cm in diameter; however, rare reports of cysts more than 5 cm are reported in the literature and are referred as “Giant epidermal cysts.” Epidermal cysts although common, can mimic other common benign lesions in the head and neck area. A thorough clinico-pathologic investigation is needed to diagnose these cutaneous lesions as they differ in their biologic behavior, treatment, and prognosis. We report a case of a giant epidermoid cyst in the scalp area of a young female patient which mimicked lipoma on clinical, as well as cyotological examination. We also present a brief review of epidermal cysts, their histopathological differential diagnosis, and their malignant transformation.

“…Subcutaneous tumors such as lipomas, neurofibromas, and hemangiomas should be included in the differential diagnosis. Ultrasonography, computed tomography, and magnetic resonance imaging may be helpful; however, histopathological examination is mandatory to reach a definitive diagnosis (2).…”
