Case History
A 28-year-old female presented to us with complaints of swelling in the scalp region since 6 months. She underwent scalp sebaceous cyst excision 8 months back. After that she developed this swelling that was associated with discharge. On examination, 4 × 4 cm size cauliflower type fungating discharging mass was found over the vertex region (Fig. 1). Within 2 days of admission this was ruptured and presented as an ulcer and the floor was covered with granulation tissue with everted edge (Fig. 2). Clinically, the patient was diagnosed to have recurrent sebaceous cyst with Cock’s peculiar tumour. She underwent excision for the same.

Discussion
Cock’s peculiar tumour is one of the complications of the sebaceous cyst. When the sebaceous cyst of the scalp ulcerates, excessive granulation tissue forms resembling fungating epithelioma, this is called Cock’s peculiar tumour[1, 2]. This tumour looks angry and sore. It is an eponym, named after the English surgeon Edward Cock [3]. This tumour resembles that of squamous cell carcinoma [4]. Treatment for this tumour is excision of the cyst as like sebaceous cyst after controlling the infection.
