Treatment options and outcomes of penile constriction devices

ABSTRACT Purpose: To study the effect of penile constriction devices used on a large series of patients who presented at our emergency facility. We explored treatment options to prevent a wide range of vascular and mechanical injuries occurring due to penile entrapment. Materials and Methods: Between January 2001 and March 2016, 26 patients with penile entrapment were admitted to our facility and prospectively evaluated. Results: The time that elapsed from penile constrictor application to hospital admission varied from 10 hours to 6 weeks (mean: 22.8 hours). Non-metallic devices were used by 18 patients (66.6%) while the other nine (33.4%) had used metallic objects. Acute urinary retention was present in six (23%) patients, of whom four (66.6%) underwent percutaneous surgical cystotomy and two (33.4%) underwent simple bladder catheterization. The main reason for penile constrictor placement was erectile dysfunction, accounting for 15 (55.5%) cases. Autoerotic intention, psychiatric disorders, and sexual violence were responsible in five (18.5%), five (18.5%), and two (7.4%) cases, respectively. The mean hospital stay was 18 hours (range, 6 hours to 3 weeks). Conclusion: Penile strangulation treatment must be immediate through the extraction of the foreign body, avoiding vascular impairments that can lead to serious complications. Most patients present with low-grade injuries and use penile constrictors due to erectile dysfunction. Removal of constrictor device can be challenging. The use of specific tools for achieving penile release from constrictors is a fast, safe and effective method. Patients with urinary retention may require urinary diversion.

Case for diagnosis. Atypical genital lesion

Abstract: We present a case of a penile lesion with a clinical appearance similar to Mondor penile disease (thrombosis of the dorsal vein of the penis) or penile sclerosing lymphangitis. Laboratory evaluation, however, showed a solid lesion, with no vascular component to Doppler ultrasonography and no treponema to immunohistochemistry. Histological and serological tests were compatible with secondary syphilis. The authors reinforce the need for the inclusion of syphilis in the differential diagnosis of penile cord injuries.

Dermoscopic and Clinical Features of Pigmented Skin Lesions of the Genital Area

BACKGROUND: The dermoscopic features of vulvar melanosis lesions are well known. To our knowledge, there are only a few case reports about dermoscopic features of pigmented genital lesions in male patients. OBJECTIVE: To evaluate dermoscopic and clinical characteristics of benign lesions of the genital area in both males and females, and to assess the distinguishing dermoscopic criteria of vulvar melanosis and atypical melanocytic nevi of the genital type. METHODS: 68 patients with pigmented genital lesions were included in this observational study (28 male and 40 female). A punch biopsy was taken from all pigmented lesions and histopathological examination was performed on all specimens. RESULTS: We histopathologically diagnosed: genital melanosis in 40 lesions, atypical melanocytic nevi of the genital type in 15 lesions, melanocytic nevi in 9 lesions, seborrheic keratosis in 4 lesions. The most frequent locations were the glans penis (19 patients, 67.9%) in males and the labia minora (19 patients, 47.5%) in females. The mean age of patients with atypical nevi (28,6 ± 11,36) was significantly lower than the mean age of patients with genital melanosis (47,07 ± 15,33). CONCLUSIONS: Parallel pattern is prominent in genital melanosis, ring-like pattern is only observed in genital melanosis. Most pigmented lesions on the genital area are solitary. Blue-white veil and irregular dots are only observed in AMNGT. According to these results, we propose that histopathological examination is performed, especially if blue-white veil and irregular dots are found by dermoscopy. .

Primary cutaneous histoplasmosis developed in the penis of an immunocompetent patient

A 70-year-old male presenting a 3-month history of genital painless erythematous nodules in the balanopreputial sulcus was referred to our service. Histopathological exam presented a chronic dermatitis with epithelioid granulomas and Grocott staining revealed numerous fungal structures with a suggestive morphology of Histoplasma sp. Cultures evidenced Histoplasma capsulatum var. capsulatum. Treatment with oral itraconazole led to complete remission of lesions.

Ulcerative penile Leishmaniasis in a child.

Penile ulcers may be caused by several different agents. Rarely, cutaneous leishmaniasis may also be accompanied by penile ulcers. We report a five-year-old boy with who had an ulcer on the glans penis. Smears from the ulcer demonstrated amastigotes, biopsy showed histopathological features of leishmaniasis and Leishmania was grown in culture. Treatment with meglumine antimoniate injections led to improvement.

Pruritic porokeratotic peno-scrotal plaques: Porokeratosis or porokeratotic epidermal reaction pattern? A report of 10 cases.

Background: Porokeratosis restricted to the genital region is rare with few cases described in the literature. Cases of porokeratosis restricted to the genital region are similar to plaque type of porokeratosis of Mibelli seen elsewhere on the body. We encountered 10 young males with pruritic plaques restricted to the peno-scrotal region, which clinically were not diagnosed as porokeratosis, but on biopsy revealed multiple cornoid lamellae, some of which were seen to arise from eccrine and follicular structures. Aims: The aim of this study is to study lesions restricted to the peno-scrotal region in males, which on biopsy showed cornoid lamellae suggestive of porokeratosis. Methods: Retrospective analysis of available data of patients who were rendered a histological diagnosis of genital porokeratosis. The database consisted of biopsies received in private consultation by the first author in the period January 2000 to March 2013. Results: Ten young men, 8 in their third decade, presented with pruritic plaques restricted to the peno-scrotal region of variable duration. The lesions were well-demarcated on the penis, but ill-defined with a rough granular surface on the scrotum. None of patients were diagnosed clinically as porokeratosis. The lesions were poorly responsive to topical steroid/antifungal treatment, but two patients showed partial improvement with oral isotretinoin. Biopsy in nine patients revealed multiple cornoid lamellae involving epidermis (6) and adnexal structures (3). One patient had a single cornoid lamella. Conclusion: The clinical and histological presentation of these patients is different from typical genital porokeratosis described in the literature and we postulate that these patients have an unusual porokeratotic reaction pattern of the epidermis with multiple cornoid lamellae.

Genital warts: comparing clinical findings to dermatoscopic aspects, in vivo reflectance confocal features and histopathologic exam

Genital warts can be diagnosed through physical examination and confirmed by histopathology. Noninvasive methods are useful for ruling out other diagnoses with no harm to the patient. In this study the clinical findings were compared to dermoscopy, reflectance confocal microscopy (RCM), and to histopathology findings, in order to determine possible patterns that can aid diagnosis of the lesion. It was possible to identify structural changes on reflectance confocal microscopy that are already known by dermoscopy, in addition to cellular changes previously seen only by histopathological examination. This study shows the use of reflectance confocal microscopy in cases of genital warts, providing important information that can be used in further studies.

Case for diagnosis / Caso para diagnóstico

Porokeratosis is a primary keratinizing disorder of unknown etiology. This disorder is characterized by the presence of centrifugally enlarging hyperkeratotic plaques, associated with the histopathological hallmark of cornoid lamellae. Genital porokeratosis is extremely rare. No more than thirty cases have been reported in the literature, including only one case of linear porokeratosis confined to the genital area. This case report describes a patient with genital linear porokeratosis, who was successfully treated with cryotherapy. Over two years of follow-up, the lesion improved and there was no evidence of recurrence or signs of malignant transformation. Nevertheless, there is a need for long-term follow-up data on recurrence and malignant transformation.

A poroceratose é uma desordem primária de queratinização, de etiologia desconhecida. Apresenta-se com lesões eritemato-acastanhadas com crista periférica e centro normal ou atrófico, e está associada ao achado anatomopatológico de lamela cornoide. O envolvimento genital nessa doença é extremamente raro. Não mais que trinta casos têm sido descritos na literatura, sendo um desses casos de poroceratose linear localizado na área genital. Descrevemos um caso de poroceratose linear genital tratado com crioterapia. Durante dois anos de seguimento, houve melhora do aspecto das lesões, sem recorrência ou sinais de transformação maligna. Entretanto, um acompanhamento a longo prazo se faz necessário.

Penile herpes zoster: an unusual location for a common disease

Herpes zoster is a common dermatological condition which affects up to 20 percent of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

Verruciform xanthoma of the penis in a young male masquerading as squamous cell carcinoma: case report

Verruciform xanthoma [VX] is a relatively rare benign lesion of unknown etiology with a predilection for oral mucosa. Penis is an uncommon location and to date only 17 cases of VX of penis have been reported. The lesion assumes importances as it can be easily mistaken for verrucous carcinoma or squamous cell carcinoma. We present herein a case of penile XV in a 25-year-old man who was referred to our institute with a histopathologic diagnosis of squamous cell carcinoma reported elsewhere. On microscopy the lesion demonstrated florid verruciform hyperplasia of the epidermis with hyperkeratosis, parakeratosis and acanthosis. There was a dense infiltrate of foam cells in the papillary dermis [a hallmark of VX], which were positive for CD68 and negative for S-100 protein. We present this case to highlight the significance of recognizing VX in extra oral location. An awareness of this entity is crucial to prevent misdiagnosis and halt inappropriate therapeutic intervention

Pápulas perláceas penianas: apresentação clínica atípica em criança / Pearly penile papule: athypical clinical presentation in a child

As pápulas perláceas penianas (PPP), também conhecidas como glândulas de Tyson, são um tipo de angiofibroma; portanto, lesões benignas.São pápulas branco-peroladas, assintomáticas, localizadas na glande do pênis e com maior incidência na idade pós-puberal. Não necessitam de outro tratamento além da informação. Neste trabalho, apresentamos um caso de PPP com localização, idade e sintomatologia atípicas, mostrando a importância da diferenciação clínica com papilomavírus humano (HPV) e outras entidades, e da realização de exame histopatológico nas lesões de diagnóstico incerto.

Pearly penile papules (PPPs), also known as Tyson's glands, are a type of angiofibroma; thus, benign lesions. They are characterized by asymptomatic pearly white papules, located on the glans penis, most often in postpubertal males. They do not require any treatment other than reassurance.At this work, we present a case of PPP with athypical localization, age and symptomathology, showing the importance of the clinical distinction with human papillomavirus (HPV) and other diseases, and the histopathologic exam on uncertain diagnosis lesions.

Doença de Mucha-Habermann (variante febril úlcero-necrótica) com acometimento mucoso exuberante: relato de caso / Febrile ulceronecrotic Mucha-Habermann disease with exuberant mucosal involvement: case report

A pitiríase liquenoide é dermatose incomum, idiopática, com espectro clínico-histopatológico onde inclui a forma varioliforme aguda (doença de Mucha-Habermann), sua variante febril úlceronecrótica e a forma crônica. Manifestações sistêmicas podem ocorrer na variante febril úlcero-necrótica, com relatos de casos fatais em adultos. Relata-se o caso de um paciente jovem, com diagnóstico clínico e histopatológico de doença de Mucha-Habermann, variante febril úlcero-necrótica, e acometimento mucoso exuberante, fato ocasional, mesmo nas formas mais graves de pitiríase liquenoide. Além do aspecto clínico inusitado, demonstra-se excelente resultado terapêutico, com a associação de prednisona e metotrexato.

Pityriasis lichenoides is a rare idiopathic cutaneous disorder, with a clinical-histopathological spectrum comprising the acute varioliform form (Mucha-Habermann's disease), its febrile ulceronecrotic variant, and its chronic form. Systemic manifestations may occur in the febrile ulceronecrotic variant, with reports of adult mortality. The case of a young male patient with clinical and histopathological diagnosis of Mucha-Habermann’s disease, febrile ulceronecrotic variant, with severe mucosal involvement - an occasional incidence even in the most severe forms of pityriasis lichenoides - is presented. In addition to the atypical clinical aspect, an excellent therapeutic result is shown with the association of prednisone and methotrexate.

Parameatal urethral cyst.

Cyst formation in the parameatal area of the urethra is an uncommon entity. It was first reported in two male cases as recently as 1956 by Thompson and Lantin. Further reports have been rare. Herein, we report a case of a 21 year-old male having a spherical, cystic swelling 1 cm in size at the external urethral meatus. The diagnosis of parameatal urethral cyst was made and the cyst was excised. Histopathological examination revealed a monolocular cyst lined with transitional cells. The postoperative period was uneventful.

A giant Condyloma accuminata.

Condyloma accuminata is not a rare disease in our country. But such a giant Condyloma accuminata is very uncommon case that we reported here. It is a type of venereal wart that commonly grows in genital region, caused by the HPV (Human papilloma virus). It is considered one of the most common sexually transmitted disease in western countries. The patient presented with cauliflower like fungating growth over the genitalia for 15 years with pain and burning sensation over the lesion for 1 month. Patient had multiple sexual partners for about 20 years. Clinically the patient was diagnosed as Condyloma accuminata. The wart was excised under spinal anesthesia and confirmed by histopathology.

Relation between the area affected by Fournier's gangrene and the type of reconstructive surgery used: a study with 80 patients

OBJECTIVE: To assess the affected skin area and the reconstructive techniques used in 80 patients affected by Fournier's gangrene. MATERIALS AND METHODS: Eighty patients ranging in age from 19 to 85 years (mean = 51) affected by Fournier's gangrene were studied. When admitted to the emergency room the patients were submitted to clinical and laboratory examinations to analyze the gravity of the case. All patients were submitted to an extensive debridement of the lesion, urinary derivation by cystostomy and colostomy whenever necessary. RESULTS: Only 13 patients (16.25 percent) died. From the 67 remaining patients, in 44 (65.6 percent) debridement was restricted to the scrotum, in 10 (14.9 percent) there has been scrotum and penile lesions and in 13 (19.3 percent) there has been a debridement of the scrotum and the perineal region. In 11 cases (16.4 percent) there was no need for reconstructive surgery with wound closing by second intention, in 16 cases (23.8 percent) reconstructive surgery was performed with mobilization of local skin, in 19 (28.3 percent) we have used skin grafts, 20 patients (29.8 percent) needed reconstructive surgery with the use of skin flaps and in 1 case (1.4 percent) there has been the use of skin flaps and grafts simultaneously. CONCLUSIONS: Fournier's gangrene is a serious pathology and should be treated aggressively with an extensive debridement of the area with necrosis. The use of precocious reconstructive surgery of the genitals present good results and tends to greatly reduce the length of hospital stay and improve the psychological conditions of these patients.

Penoscrotal Reconstruction Using Groin and Bilateral Superomedial Thigh Flaps: A Case of Penile Vaselinoma Causing Fournier's Gangrene

Penile augmentation by the injection of mineral oil provokes many serious, undesirable effects. Although there are reports of complications such as deformity, ulceration, necrosis, and erectile dysfunction, Fournier's gangrene resulting from the injection of petroleum jelly into the penis has not been reported. Here, we present a 42-year-old man with penile vaselinoma causing Fournier's gangrene which was treated successfully with aggressive surgical debridement, followed by penoscrotal reconstruction using groin and bilateral superomedial thigh flaps.
