Innervation of pelvic viscera in the rat. Evoked potentials in nerves to bladder and penis (clitoris).

In 29 rats, responses evoked by pelvic and hypogastric nerve stimulation were recorded from postganglionic nerves to bladder and penis (clitoris). Responses to pelvic nerve stimulation had nonsynapsing and synapsing components. The nonsynapsing component was relatively large in main nerve to penis and small in lateral nerve to penis and nerves to bladder. Pelvic nerve fiber synapsing on pelvic ganglion neurons to bladder had a large subliminal fringe, while fibers synapsing on neurons supplying penis (clitoris) had a small subliminal fringe. Recruitment was greater in nerves to bladder and lateral nerve to penis (clitoris) compared to main nerve to penis (clitoris), indicating more synapsing fibers in the former nerves. Almost all hypogastric fibers to bladder were direct. A small subliminal fringe was demonstrated for hypogastric fibers synapsing on neurons supplying penis. No subliminal fringe was evident for the bladder. Pelvic and hypogastric nerve interaction on pelvic ganglion neurons could not be demonstrated with either single shock or tetanic trains of conditioning stimuli. With antidromic stimulation, conduction velocities of afferent fibers in pelvic nerve ranged from 0.15 m per sec to 2.9 m per sec. In hypogastric nerve they ranged from 0.35 m per sec to 2.8 m per sec.

Immunohistochemical study of neuropeptide Y-containing nerve fibers in the human clitoris and penis.

The occurrence and distribution of neuropeptide Y in the human clitoris and penis was investigated by light immunohistochemistry. Neuropeptide Y-containing nerve fibers were detected in the tunicae of arteries and veins as well as among trabecular smooth muscle. The distribution pattern of the peptide was similar in both organs although a higher density of immunoreactive nerve fibers was detected in the penis. The immunolocalization of neuropeptide Y was also compared with that of neuron-specific enolase, a neuronal marker which labels the entire nerve network. It is suggested that neuropeptide Y is involved in the physiology of the penis and the clitoris, affecting vascular and nonvascular smooth muscle activity.

Post-circumcision epidermoid inclusion cysts of the clitoris.

We describe our experiences during the last 5 years with 19 cases of epidermoid inclusion cysts of the clitoris resulting from circumcision. There were 14 children and 5 adults. The management consisted of complete excision of the cyst, and reconstruction of the clitoris, wherever possible.

Angiokeratoma of the clitoris: a subtype of angiokeratoma vulvae.

A 24-year-old married woman had an angiokeratoma of the vulva measuring 3 x 3 x 4 mm localized at the clitoris. The nodule was noticed when she was pregnant with her first child. This tumor grew with occasional tenderness and bleeding during pregnancy, but its size did not change after delivery. The growth of this tumor might be attributable to an increase in venous pressure or serum progesterone levels; therefore this disorder might be classified as a subtype of angiokeratoma of the vulva. This is the first case of angiokeratoma localized at the clitoris.

Postnatal development of vagina, clitoris and urethral glands of the golden hamster.

We have made a histological study of the postnatal development of the clitoris, preputial glands, urethral glands and vagina of the golden hamster. The 'phallic groove' of the clitoris is closed at 10 days of life, then the urethra has a cuboidal stratified, a stratified squamous and a stratified keratinized epithelium. The preputial glands are composed of branched saccular glands. These glands develop, with few changes during their maturation period. Formation of the urethral glands begins at 5 days and the alveoli are fully developed at puberty. The hamster vagina has two origins; the upper part is Müllerian, the caudal part is sinusal. The wall of the Müllerian vagina has a cylindrical epithelium at birth, which becomes 'double epithelium' at puberty and thereafter changes cyclically in connection with the estrous cycle. The sinusal vagina is solid at birth, its lumen being formed in the first 10 days of life and its wall having a cuboidal stratified epithelium. At 15 days it becomes a stratified keratinized epithelium, which will later line the vaginal pouch. At the 5th day, an ectodermic invagination (stratified keratinized epithelium) is observed in the zone of the future introitus. At the time of vaginal opening this zone forms the distal segment.

Angiokeratoma of the clitoris.

A 25-year-old woman, multigravida, presented with a dark ulcerated tumor of the clitoris. Histologic examination demonstrated an angiokeratoma, a benign telangiectatic vascular tumor. To our knowledge, this is the first report of angiokeratoma of the clitoris and only the fifth describing vascular tumor of this organ. The clinical differential diagnosis of angiokeratoma and of clitoral tumors includes malignant neoplasms such as melanoma. Biopsy with histologic examination is, therefore, recommended to ensure appropriate treatment of these unusual tumors.

Pelvic lymphadenectomy in women with carcinoma of the clitoris.

Thirty-three women with carcinoma of the clitoris underwent surgical therapy, and 12% subsequently developed pelvic recurrence. However, none of the 18 patients without initial evidence of inguinal node metastases developed a pelvic recurrence. Of the 15 women with initial evidence of inguinal node metastases, 26.6% developed pelvic recurrence. It is, therefore, concluded that the addition of the routine use of pelvic lymphadenectomy to radical vulvectomy and bilateral inguinal lymphadenectomy in women with carcinoma of the clitoris is not warranted and that only those patients with histologically proven inguinal node metastases should undergo pelvic lymphadenectomy. If pelvic node metastases are documented, it is suggested that such patients receive postoperative pelvic irradiation.

Epithelioid hemangioendothelioma of the clitoris: a case report with immunohistochemical and ultrastructural findings.

A 30-year-old woman was referred for evaluation of a small nodule of the clitoris. This was subsequently diagnosed as epithelioid hemangioendothelioma. This rare vascular tumor of intermediate malignancy has not been previously described in the vulva. The patient underwent a modified radical vulvectomy and bilateral inguinal lymph node dissection, and subsequently received photon therapy. She is alive with no evidence of disease 27 months after diagnosis.

[The sensitive nerve endings of the clitoris of the sow (Sus scrofa domesticus)].

Neural receptors of the porcine clitoris were examined using light and electron microscopy. Perfusion with ink allowed study of the unique vascular arrangement associated with the genital corpuscles. Sensory nerve-endings were generally rounded and formed a morphologically and structurally characteristic unit. They were composed of a network of primarily non-myelinated nerve fibers and flat cells. Between these structures, isolated small blood vessels were embedded amongst collagen fibers and amorphous material. An external capsule of variable thickness always surrounded the structures. A complex arrangement of vessels in the center of the capsule was formed by a subpapillary mesh. The same arrangement was seen in the morphologically comparable penile genital corpuscles of the same species. Based on the particular arrangement of blood vessels and nerve fibers in the genital corpuscles, some authors postulate the presence of a neuro-vascular glomerulus.

[Reconstruction of the female urethra using the roots of the clitoris. Eleven cases (author's transl)].

In 10 cases of obstetric and surgical necrosis of the urethra and in one of congenital aplasia, the canal was reconstructed using as an intermediate layer the roots of the clitoris, freed and applied. In the ten cases in which treatment has been completed, continence was restored in 8, either with one operation only (3 cases), or with the addition of various procedures for suspension of the bladder neck using autografts (5 cases).

Neurofibroma of the clitoris. A case report.

We report an unusual case of clitoral hypertrophy due to neurofibromatosis of the external genitalia. Because of no definite skin signs or other nervous or osseous symptoms such as are commonly found in neurofibromatosis, the patient was at first suspected of being a case of hermaphroditism. Finally, the disorder was properly diagnosed after laparotomy followed by clitorectomy. This patient seems to be the 12th case of clitoral neurofibroma reported in the English literature.
