Pediatric Penile Non-Involuting Congenital Hemangioma With an Associated Pyogenic Granuloma: Surgical Management of a Rare Vascular Anomaly.

Vascular anomalies include both tumors and malformations. Infantile hemangiomas are the most common benign vascular tumor of infancy that proliferate after birth and eventually involute. By contrast, congenital hemangiomas are formed at birth and are categorized into three groups: rapidly involuting, partially-involuting, and non-involuting congenital hemangiomas (NICH). NICH do not regress and grow with age. Pyogenic granulomas, another acquired vascular tumor, develop over vascular lesions and cause bleeding. Primary treatment options for NICH and pyogenic granulomas are surgical resection. Here, we report a case of a NICH with a co-existing pyogenic granuloma involving the penile shaft and scrotum treated surgically.

Congenital Penile Rhabdomyosarcoma on FDG PET/CT.

Primary penile malignancy is uncommon. Congenital primary penile rhabdomyosarcoma diagnosed in an infant is extremely rare. We present the FDG PET/CT findings in a 1-month-old boy with penile mass. The images showed hypermetabolic lesion at the base of the penis and left inguinal lymph node. Pathological examination demonstrated rhabdomyosarcoma.

Congenital primary penile teratoma in a child.

Teratomas rarely present as a pediatric congenital primary penile mass. We describe a 14-month-old boy with a blister-like mass on his distal left penis. The subcutaneous mass measured 1.5 cm (length)×1.0 cm (width)×1.2 cm (height) on ultrasonography. There were clear margins between these structures and the lesion. At the age of 5 years, he received an extirpation surgery. Histologic analysis revealed that it was a mature teratoma. In our view, surgical resection should be the treatment of choice for a pediatric penile mass with the alertness of teratomas because of the possibility of malignant alteration and invasion of adjacent structures till unresectable.

Dermoid cyst of the penis.

A dermoid cyst of the penis has not been documented previously in the literature. We report a young Caucasian who had an important swelling of the penis dating back several months. On examination a subcutaneous mass on the dorsal aspect of the shaft and prepuce was present. A cutaneous sinus discharging purulent material was also noted above the mass. Laboratory tests including serology for syphilis and bacteriologic examination were negative. An excisional biopsy revealed a nodular lesion in the subcutaneous tissue with tufts of hair emerging from the surface. Histopathologic examination disclosed granulation tissue containing fragments of hair surrounded by granulomatous infiltrate. Serial sections allowed identification of a subcutaneous cyst. The wall was epidermoid and connected with several pilosebaceous units. A sinus tract lined by stratified squamous epithelium contiguous with the epidermis was also noted. Clinical and histopathologic differential diagnoses are discussed. Evidence for a congenital origin of this condition is given.

Congenital genitourinary hemangiomas in a patient with the Klippel-Trenaunay syndrome: management with the neodymium:YAG laser.

The Klippel-Trenaunay syndrome is an unusual congenital anomaly characterized by cutaneous hemangiomas, multiple varicosities, soft tissue hypertrophy and, rarely, gastrointestinal or genitourinary hemangiomas. The large bladder as well as multiple penile hemangiomas in our patient were treated successfully with the neodymium:YAG laser with minimal morbidity.

Congenital endodermal sinus tumor of the penis.

Congenitally occurring endodermal sinus tumors are very rare and frequently occur in association with teratomatous growths. The most common location for these tumors in infancy is the gonads. Tumors of the penis are rare in any age group. As far as we know, this tumor has never been reported in the penis. A 17-month-old baby boy was noted to have a pimple-like lesion at the corona of the glans penis. This was stationary and ignored for a year. At this point, the lump began increasing in size. A further delay of 6 months elapsed before a definitive diagnosis was made. This case emphasizes that any nodule in this area in the neonate is ignored with jeopardy.

Recurrent penile condylomata acuminata in a 17-month-old boy.

Penile condyloma acuminatum is a rare pediatric entity. We report on a 17-month-old boy with penile and urethral condyloma acuminatum. The presence of cervical dysplasia in a histological setting suggestive of condyloma in his mother supports congenital acquisition of the disease. Histological and histochemical evidence for a viral etiology of the disease in the mother and patient is presented.

Epidermal cyst of median raphe.

Cysts of the penis are rare and references to them in standard textbooks are sketchy. A case report of a congenital epidermal cyst of the median raphe of the penis is presented; therapy involved excision of the mass. Review of the literature is given.
