| Introduction|| |
A lipoma is a slow growing tumor composed of fat cells of adult type. Lipomas may be encapsulated or diffuse. Lipomas are among the most common benign tumors. They can occur anywhere in the body where fat is found and hence the title of the "universal tumor" or the "ubiquitous tumor." The head and neck area, abdominal wall and thighs are particularly favored sites. Lipoma present as soft, painless, subcutaneous lumps. Most lipomas are excised for cosmetic reasons. Only two cases of lipoma of penis have been reported in the literature so far; hence this case is being reported due to its rarity and unusual presentation.
| Case Report|| |
A 35-year-old male patient presented to the surgery out-patient department with the complaints of a rounded swelling over the shaft of penis for past 6 months and bilateral enlargement of the scrotum for last 8 months. The lesion on the penis had gradually increased in size. It was not associated with pain or fever. The patient was sexually active.  On general examination, there was no significant finding and the inguinal lymph nodes on both sides were normally palpable. On examination of penis, a soft, non-tender, well-circumscribed swelling of about 2 cm in diameter with a smooth surface, mobile, not fixed to skin or deeper structures was noted [Figure 1]. On examination of the scrotum, bilateral scrotal swellings noted. The upper pole of the scrotum could be easily reached. The scrotal swellings were non-tender, fluctuant and translucent. Routine blood and urine examination was normal. Fasting blood sugar and post-prandial blood sugar, serum creatinine and urea levels were normal. Fine-needle aspiration cytology was not carried out for the want of excisional biopsy and accurate diagnosis. Ultrasonography of scrotum revealed bilateral hydrocele with normal testes. A provisional diagnosis of lipoma of penis and bilateral idiopathic hydrocele was made. Under local anesthesia excision of penile swelling with bilateral eversion of sac was carried out without putting a drain. The resected swelling on gross examination was found encapsulated and seemed to be lipoma. It was sent for histopathological examination which confirmed the diagnosis of lipoma. The post-operative period was uneventful. In 2 months follow-up the penis was found normal in shape and the scrotum was shrunken near to normalcy.
| Discussion|| |
Lipomas are benign lesions included in the wide spectrum of swellings in the penis. Although asymptomatic and of low objective significance they often cause esthetic and psychogenic problems. Patients presented with sexual dysfunction which later turned out to be psychogenic. Differential diagnosis include angiomyolipoma  of penis, epidermoid cyst  of glans penis, parametal cyst  of glans penis. The reason for underreporting of such cases might be small size, no associated symptoms or relatively clinically insignificant presentation.
