INTRODUCTION Up to 30% of squamous cell carcinomas of the penis arise from a lichen sclerosus, but very few reports in which lichen planus was the preexisting lesion have been published. We report a male with verrucous carcinoma of penis that developed in an area of lichen planus. CLINICAL CASE A 53-year-old male presented with an exophytic tumor on the glans penis that had been present for a...

Subincision of the penis is a traditional ritual mutilation unique to the Aborigines, the indigenous people of Australia. The mutilation is a urethrotomy in which the undersurface of the penis is incised and the urethra slit open lengthwise. Subincision is one element in the initiation of Aboriginal youths. In later ceremonies, repeated throughout adult life, the subincised penis is used as a s...

Micropenis is part of a larger group of conditions broadly known as inconspicuous penis; however, it is fundamentally different from the other diagnoses in this group, such as webbed penis and buried penis, in that the underlying problem is the size of the penis itself, not with the surrounding and overlying skin. This condition is usually the result of a defect in the hypothalamic-pituitary-go...

INTRODUCTION Penile fracture has been reported with sexual intercourse, masturbation, rolling over or falling on to the erect penis. Classically the history is with a sudden snap, pain, detumescence and a hematoma of the penis with deformity. Immediate surgical treatment is recommended. The patients may delay the admission due to fear and embarrassment or the condition may usually be underrepor...

^ f Of the five books I have been able to refer to Erichsen and Rose and Carless do not appear to mention the injury, Spencer and Gask merely mention it, while Treves' is the only work that gives any details, Neal's Medical Digest refers to five cases, of which through the courtesy of the Librarian of the Royal College of Surgeons, I have been able to obtain summaries. 1. My first case was a Go...

Penile carcinoma frequency varies widely in different parts of the world and comprises 1-10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%-10% of all the variants. The other histologic...

The erection mechanism of the penis in most vertebrates is blood vascular. A major evolutionary transition occurred in birds, where the erection mechanism changed from blood vascular to lymphatic. Within birds, however, the erection mechanism of the ratite penis has remained unknown. Early work suggested that the erection mechanism in ostrich Struthio camelus was blood vascular while no descrip...

BACKGROUND Langerhans cell histiocytosis affects mainly young children and features an accumulation of CD1a+ dendritic Langerhans cells in the bone, skin, and other organs. A few cases of Langerhans cell histiocytosis on the penis have been reported in the literature. We present a case of Langerhans cell histiocytosis on the penis and review the similar cases in the literature. CASE PRESENTAT...

Testicular or scrotal involvement has been reported in children with Henoch-Schonlein purpura (HSP), but there are very few reports on penile involvement. We report the initial and follow-up ultrasonographic findings of scrotal and penile involvement of HSP in a 5-year-old boy. On ultrasonography, scrotal soft tissue thickening and epididymal swelling with increased vascularity were noted, and ...

Introduction Hypospadias is a wide spectrum of abnormalities involving the inferior surface of the penis and having in common a urethral opening that lies on the inferior surface of the penis, (hypo = under; spadias = opening or rent). The spectrum of hypospadias anomalies includes an abnormal urethral opening, chordee (ventral curvature of the penis), an incomplete prepuce, rotation of the pen...
