ABSTRACT
Objectives: The purpose of this study was to see the effect of parenteral testosterone injection on penile length, glans diameter, and diameter at the base of the penis in hypospadias patients before surgery. Material and Methods: The study was conducted from September 2019 to March 2021. This study comprised a total of 20 hypospadias patients. At a dose of 2 mg/kg body weight, an injection testosterone propionate was administered deep intramuscularly in three doses with a 3-week gap before reconstructive surgery. Before surgery, the penile length, glans diameter, and penile diameter at the base of the penis were all measured. Results: The mean increase in penile length, glans diameter, and diameter at the base of penis following parenteral testosterone therapy was 1.07 ± 0.23 cm (P < 0.001), 1.01 ± 0.46 cm (P < 0.001), and 0.92 ± 0.12 cm (P < 0.001), respectively. All three measurements were statistically significant. Conclusion: Intramuscular testosterone increased penis size, glans diameter, and penile diameter without causing any notable side effects. Development of fine pubic hair, acne, and aggressiveness is minor adverse effects.
ABSTRACT
SUMMARY: The corporo-glans ligament is the ligament connecting the corpus cavernosum and the glans of the penis. The anatomical description of the corporo-glans ligaments shape is still uncertain, this knowledge affects penile reconstructive procedures. The anatomy of the corporo-glans ligament was analyzed and recorded via observing sagittal sections of 10 different penile P45 plastination sections. According to the P45 plastination sections, the corporo-glans junction displayed a fibrous tissue band connecting the distal ends of the two corpus cavernous (CC) with the glans penis (GP). The fibrous band was a round-obtuse shape and ran deep into the glans of the penis and occupied about 2/3 of the whole GP. The original end was laid in a socket embedded in the GP. The density of the fibers of the ligament at the original end close to the tunica albuginea was less than that of the other parts. The fibers originating from the tunica albuginea, directly extended to the blind end of the two CC, covering the distal end of the two CC.
El ligamento cuerpo cavernoso-glande es el ligamento que conecta el cuerpo cavernoso y el glande del pene. La descripción anatómica de la forma de los ligamentos cuerpo cavernoso -glande aún es incierta; este conocimiento afecta los procedimientos reconstructivos del pene. La anatomía del ligamento cuerpo cavernoso-glande se analizó y registró mediante la observación de 10 secciones sagitales diferentes del pene a través de plastinación P45. Según las secciones de plastinación, la unión cuerpo-glande mostraba una banda de tejido fibroso que conectaba los extremos distales de los dos cuerpos cavernosos con el glande del pene. La banda fibrosa tenía una forma redonda y obtusa y se adentraba profundamente en el glande del pene ocupando alrededor de 2/3 de él. En su origen se coloca en un espacio profundo en el glande del pene. La densidad de las fibras del ligamento cuerpo cavernoso-glande en su origen cercano a la túnica albugínea era menor que el de las otras partes. Las fibras que se originan en la túnica albugínea, se extienden directamente hasta el extremo ciego de los dos cuerpos cavernosos, cubriendo el extremo distal de estos.

ABSTRACT
Resumen 22. El linfangioma circunscripto (LC) es una afección rara y benigna, caracterizada principalmente por la malformación de los vasos linfáticos de la piel. De etiología congénita o adquirida,esta última debido a causas secundarias como radioterapia, infecciones o procedimientos quirúrgicos. 23. Presentamos el caso de un paciente de 75 años de edad, con antecedente quirúrgico de fimosis a los 29 años, y posterior desarrollo de linfangioma circunscripto de glande diagnosticado 46 años después. El tratamiento definitivo planteado en interconsulta con Urología fue la resección quirúrgica, motivados por la escasa frecuencia de recidivas cuando se usa este método.
Summary 27. Circumscribed lymphangioma (CL) is a rare and benign condition, characterized mainly by malformation of the lymphatic vessels of the skin. It has a congenital or acquired etiology, the latter due to secondary effects such as radiotherapy, infections or surgical procedures. 28. We present the case of a 75-year-old patient, with a surgical history of phimosis at 29 years of age, and subsequent development of circumscribed lymphangioma of the glans penis diagnosed 46 years later. The definitive treatment proposed in consultation with Urology was surgical resection due to the low frequency of recurrences.
ABSTRACT
There is no safe and effective standard method for glans penis augmentation. Furthermore, there has been scant research on glans penis augmentation due to a poor understanding of glans anatomy, technical difficulty, and a lack of suitable substances for augmentation. Cross-linked dextran gel is a newly developed filler for soft-tissue augmentation. We evaluated the efficacy and safety of using a novel technique to inject cross-linked dextran gel for glans penis augmentation during a 24-week follow-up study. This prospective, single-arm, multicenter study enrolled twenty healthy adult men who underwent glans penis augmentation between June and August 2013. Cross-linked dextran gel was injected into the glans penis using a simple and easy technique. The sizes of the glans penis and individual satisfaction were assessed. Any adverse event was also reported. A total of 18 individuals were analyzed; two of them were lost to follow-up. The mean procedure time and injected volume were about 30 min and 6.6 ± 0.9 ml, respectively. The mean surface areas of the glans at baseline and 24 weeks were 20.0 ± 3.5 cm2 and 33.6 ± 5.4 cm2, respectively, representing a mean increase of 68.7% ± 14.0% (P < 0.001). Sixteen individuals (88.9%) were satisfied with the outcomes, and none were dissatisfied. There were no serious adverse events during the study. Cross-linked dextran gel injection for glans penis augmentation was easy and showed a significant augmentative effect on the glans penis, good durability, and was well tolerated without serious adverse events. Therefore, cross-linked dextran gel injection may be an effective, new technique for glans penis augmentation.
ABSTRACT
Epidermoid cysts are benign lesions occurring anywhere in the body, but it is a rare entity over glans penis. Even though a few cases are been reported in adult age group, epidermoid cyst occurring at glans penis in young age is very rare. The etiology in penile area is not specific, but it may represent a monolayer teratoma of germ cell origin or an abnormal embryogenic closure of the median raphe. Being benign its harmless, but secondary infections are common which gives an indication for surgical removal of the cyst. Here, we report a case of epidermoid cyst in a 14-year-old boy who came with painless swelling over the glans penis.
ABSTRACT
Tuberculosis is a very common disease especially in developing countries but primary tuberculosis of penis is extremely rare. Here we are presenting a case of Primary tuberculosis of glans penis of 82 years male.
ABSTRACT
The present study analyses the glans penis and baculum morphology of three Brazilian tuco-tucos, Ctenomys torquatus Lichtenstein, 1830, Ctenomys minutus Nehring, 1887 and Ctenomys flamarioni Travi, 1981, in order to identify possible variations and understand some more about this taxonomically complex group. We used fixed penis from 15 previously listed adult specimens. For a more detailed baculum analysis, the penis underwent dissection and diaphanisation, whereas to analyse the glans penis surface we used Scanning Electron Microscopy (SEM). Results showed striking differences in baculum morphology among the three species. While C. minutus have a particular V-shaped proximal baculum tip, C. flamarioni baculum is thin throughout the shaft with rounded proximal and distal tips. Ctenomys torquatus have a shorter and larger baculum, similar to what has previously been described for the species. Glans penis surface microstructure analyses also revealed inter-specific differences, with penial spines varying in shape, size and, especially density. Although C. torquatus has a relatively small penis, it has the largest penial spine density, which suggests a more complex penial ornamentation in this species.
O presente estudo analisa a morfologia do glans penis e do baculum de três tuco-tucos do Brazil - Ctenomys torquatus Lichtenstein, 1830, Ctenomys minutus Nehring, 1887, e Ctenomys flamarioni Travi, 1981 - com a finalidade de identificar possíveis variações e elucidar mais sobre grupo taxonômico complexo. Foram usados pênis fixados de 15 indivíduos adultos das espécies listadas anteriormente. Para uma análise mais detalhada do baculum, o pênis foi submetido a dissecções e diafanização, enquanto que, para a análise da superfície do glans penis, foi usada a técnica de microscopia eletrônica de varredura (MEV). Os resultados exibiram significativas diferenças na morfologia do baculum entre as três espécies. Enquanto C. minutus apresenta um baculum com uma ponta em forma de V característica, o baculum de C. flamarioni é fino ao longo do osso, com as pontas proximal e distal arredondadas. Ctenomys torquatus apresenta um baculum mais curto e largo, similar ao descrito anteriormente para a espécie. Análises da microestrutura na superfície do glans penis revelaram diferenças interespecíficas, com os espinhos penianos variando em forma, tamanho e, especialmente, densidade. Apesar de C. torquatus ter um pênis relativamente pequeno, apresenta a maior densidade de espinhos penianos, o que sugere uma complexa ornamentação peniana nesta espécie.

Milia are small, superficial keratin cysts believed to be derived from the pilosebaceous follicle, which arise most commonly on the cheeks and eyelids. We report a case of milium occurring on the glans penis in a 18-year-old man, who had a solitary dome-shaped, 2x2 mm sized, yellowish papule. The histopathological examination showed a small keratin-filled, intradermal cyst. The cyst was lined by a stratified epithelium that was a few cell layers thick. This is the first case report in the Korean dermatological literature of milium occurring on the glans penis without coexistence of other dermatoses.

We describe a case of temporary ischemic change of the glans penis after circumcision. A 36-year-old male exhibited an ischemic change in the color of the glans penis the day after receiving a dorsal penile nerve block for circumcision. After the third day, the color of the glans changed from black to dark brown. After 7 days, the glans returned to near normal skin color without other sequelae.

We report a case of a 44 year-old man with porokeratosis of Mibelli, who presented with a 10 year history of a 1 cm diameter, well-circumscribed, erythematous, scaly patch with an elevated border on his glans penis. Histologic examination revealed a typical cornoid lamella and absence of an underlying granular layer. The localized type of porokeratosis of Mibelli is most commonly found on the limbs: however, the face, lips, mucosal surfaces, or genital area may instead be involved. We report a case of porokeratosis of Mibelli confined to the glans penis, a very rare site.

Median raphe cysts are rare mid-line developmental cysts, which can arise at any point between the external urethral meatus and the anus. They most commonly affect the ventral aspect of the penis, usually near the glans. They tend to be solitary, unilocular cysts, and the inner lining is usually composed of pseudostratified columnar epithelium. We present a case of a 3-year-old boy with a median raphe cyst affecting the glans penis. The cyst, located near the urethral meatus, was slightly pruritic and 0.3cmx0.3cmx0.1cm in size. A shave biopsy, followed by CO2 laser ablation was performed, and histopathological examination revealed a unilocular cyst lined with pseudostratified columnar epithelium, which showed decapitation secretion in part. For 2 years fallawing the shave biopsy, no clinical evidence of recurrence has been observed.

Two cases of rare histologic subtypes of carcinomas involving glans penis are reported. Both contained two distinct cellular differentiation, squamous cells and mucin-producing cells. The first case was a 34-year-old Thai male with chronic ulcer at penis, showing predominant squamous cell carcinoma with interspersed small sheets of mucin-producing cells without discrete glandular structure, thus designated as “muco-epidermoid carcinoma”. The involved inguinal lymph node revealed both squamous and mucin-producing cells. Another case is a 39-year-old Thai male with penile, histologicaly proved to be carcinoma mainly constituted by malignant sqlignant part and focal glandular differentiation. The glands lined by colummer cells contained intraluminal and intracellular mucin. The bilateral sentinel lymph nodes were negative for malignancy. The immunoperoxidase staining for carcinoembryonic antigen was positively marked with mucin-producing cells in both cases. In addition, transmission electron microscopic study of mucoepidermoid carcinoma identified three populations of cells, namely squamous cells with tonofilament, mucin-producing cells with microvilli, and lastly intermediate cells bearing dual differentiation. These unusual carcinoma of glans penis are extremely rare conditions of unknown origin with a poorly defined prognosis. Discussion and review literature on the histologic definition and origin of these tumors are included.
ABSTRACT
PURPOSE: Soft-tissue augmentation using hyaluronic acid (HA) gels is widely used in dermatology and plastic surgery. We performed this study to determine the feasibility of using HA gel to augment the glans penis. MATERIALS AND METHODS: In experiment I, 0.2 cc of HA gel was injected into the dermis of the glans penis of 25 New Zealand White rabbits via a 27-gauge needle. At 3, 7, 14, 30, and 90 days after injection, the histologic changes in the penis and systemic adverse effects were evaluated. In experiment II, 0.5 cc of HA gel was injected into the dermis of the glans penis of 14 Beagle dogs. Two weeks later, an additional 0.2 cc was injected in 7 of the dogs. For 6 months, the changes in the injected area were grossly evaluated using a 10-point visual scale, and at the end of the study, histologic changes were also evaluated. At autopsy, lung, liver, and spleen were studied for systemic adverse reactions. RESULTS: In the dogs receiving double injections, 85% to 90% of the initial volume was maintained at 6 months, with HA being identified in the lamina propria of the glans penis. Encapsulated material was confirmed to be HA by alcian blue stain and hyaluronidase immunohistochemical stain. No systemic adverse reaction was noticed in any animal. CONCLUSIONS: Hyaluronic acid gel is safe and effective for augmentation of the glans penis. Booster injection enhances the injected volume and facilitates injection of HA.

Verrucous carcinoma is a variant of well-differentiated squarmous cell carcinoma. Although this tumor is well-documented in the oral cavity, its occurrence on the glans penis is rare. It is a relatively nonaggressive tumor which seldom metastasizes to the resional lymph node or distantly. With proper treatment, the prognosis is excellent. We have experienced a case of verrucous carcinoma arising on the glans penis with the previous insertion of paraffin and penile prosthesis for the augumentation of penis, which was treated with total phallectomy. We report this case with a review of literature.

PURPOSE: We evaluated the effect of injectable hyaluronic acid gel(HA) for augmentation of the glans penis and treatment of premature ejaculation. MATERIALS AND METHODS: In 139 patients with premature ejaculation, dorsal neurectomy(Group I; n=25) and glandular augmentation using HA(Group II; n=114) were done. Six months after each procedure, ejaculatory latency, penile vibratory threshold, and patient and partner satisfaction were assessed in both groups. RESULTS: There was no significant difference in preoperative ejaculation time in the two groups, being 89.2+/-40.3 sec in Group I and 96.5+/-52.3 sec in Group II. Postoperatively, ejaculatory latency was significantly increased, to 235.6+/-58.6 sec in Group I and 324.2+/-107.6 sec in Group II(p<0.01). The postoperative vibratory threshold was also significantly increased in both groups(p<0.01). Satisfaction was expressed by both the patient and his partner in 68%(17/25) and 44%(11/25), respectively, in Group I and 79.8%(91/114) and 64.0% (73/114) in Group II. The maximal glandular girth was significantly increased, from 9.2+/-0.6 cm to 11.0+/-0.4 cm, in Group II. CONCLUSIONS: Glandular augmentation with injectable HA gel appears to be very effective for the treatment of premature ejaculation. Glandular augmentation with a bulking agent is anticipated to replace the hazardous, irreversible dorsal neurectomy.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and the cyst wall of this tumor consists of columnar to cuboidal cells with a decapitation secretion indicative of apocrine secretion. A 5-year-old boy had a translucent, flesh-colored cystic nodule, 5x2x2mm in size, on the glans penis near the urethral meatus for 4 years. Although apocrine hidrocystoma of the glans penis is very rare, characteristic histopathological features make it easy to diagnose as apocrine hidrocystoma of glans penis, which should be differentiated from the median raphe cyst of the penis.

Premature ejaculation (PE) has been thought to be psychological in the majority of patients. With few exceptions, organic conditions are rarely implicated. We investigated the possible role of sensory function in patients with primary PE to determine whether or not there is an etiologic basis for PE: We performed somatosensory evoked potentials (SEP) from the penis in 34 patients with primary PE and in 30 normally potent men. The latencies and amplitudes of the evoked potentials were measured by two different places in stimuli, with one at penile shaft (DNSEP) and the other at the glans penis (GPSEP). The mean latency of DNSEP was 1.51 msec. shorter in the patient group than the normal subjects, and the mean latency of GPSEP was significantly shorter (6.80 msec.) in the patient group than the normal subjects. The mean amplitude of GPSEP was lower than that of DNSEP in both groups. However, the mean amplitudes of DNSEP and GPSEP in patients with PE were significantly higher than that of normal subjects. With these results we conclude that patients with PE have a glans penile hyperexcitability. A glans penile hyperexcitability may give rise to an uncontrolled ejaculation, which is thought to be an organic implication for PE.

We report a case of penile lymphangioma circumscriptum developed in a 22- year-old male soldier. Rice-sized papule on glans penis was noted at birth and progressed to yellow straw-colored, peanut-sized, asymptomatic grouped papulovesicles resembling frog spawn. The predilection sites of lymphangioma circumscriptum are the abdomen, axilla and tongue. Glans penis is a very rare site. Histopathologic findings showed papillornatosis, hyperkeratosis and cystically dilated lymph vessels lined by a single layer of endothelial cells.
