SQUAMOUS CELL CARCINOMA GROWING ALONG THE MARGINS OF RESECTED EPIDERMOID CYST

Abstract

ABSTRACT:

We report case of 27 years old male of a rare complication of epidermoid cyst with malignant transformation into squamous cell. Patient underwent surgery 4 months back for resection of epidermoid cyst. The patient presented post-operatively to our setup when he started having pain and swelling at surgical site which was growing progressively. Initial investigations of CT and MRI were done which showed imaging features similar to epidermoid cyst. Re-exploration surgery and histopathology confirmed keratin pearls which are seen in epidermoid cyst. On follow-up, the imaging not only showed post-surgical complications but also interval development of nodular and enhancing masses in the surgical bed. Patient underwent surgery again for post-operative complications. Biopsy was taken from tumor site. Histopathological slides of squamous cells with keratin pearls correlated with our findings of squamous cell carcinoma on imaging. Fewer cases of epidermoid cyst’s complication into malignancy are reported in literature. Our purpose is to highlight one of such cases.
