Recurrent perianal abscess secondary to cutaneous B-cell lymphoma

Abstract

Fistula-in-ano lies at the chronic end of the spectrum of perianal suppuration which is responsible for waxing and waning coarse of the disease. Recurrent infection of the fistulous tract is responsible for off and on abscess formation. Recurrent abscess formation without a fistula is a very rare entity. Here, we present a case of recurrent perianal abscess without a perianal fistula. A 45-year-old male with renal transplant on immunosuppression presented with recurrent perianal abscess which was drained multiple times and prescribed antibiotics as per culture sensitivity. Magnetic resonance imaging was Performed which did not reveal any fistula formation. The patient was subjected to a biopsy of the lesion which came out to be a B-cell lymphoma. The patient was successfully treated by a multidisciplinary team at our tertiary care center. With this case report, we conclude that recurrent abscess formation in perianal area in an immunosupressed patient may be due to an underlying cutaneous lymphoma. This disease needs multidisciplinary approach for successful management.
