Leiomioma vulvar de localización en la glándula de Bartolino: un dilema diagnóstico / Vulvar leiomyoma located in Bartholin's gland: a challenging clinical case

Resumen ANTECEDENTES: Los leiomiomas son tumores benignos que se originan en las fibras musculares lisas. La mayor parte de los leiomiomas del aparato genital femenino se localizan en el útero. La localización extrauterina es excepcional, la incidencia del leiomioma vulvar es del 0.07%. Estos tumores del músculo liso suelen ser indoloros, de crecimiento lento y pueden aparecer en mujeres de cualquier edad. OBJETIVO: Reportar un caso de leiomioma vulvar que, por su baja incidencia y similitud clínica con otras lesiones, como el quiste de la glándula de Bartolino, pueden conducir a un diagnóstico erróneo inicial. Además, efectuar una revisión bibliográfica que aporte conocimiento a su diagnóstico y tratamiento. CASO CLÍNICO: Paciente de 52 años, con una masa vulvar de años de evolución y un diagnóstico equívoco inicial de quiste de la glándula de Bartolino. La paciente fue intervenida mediante escisión quirúrgica y estudio histopatológico posterior. El diagnóstico definitivo fue de leiomioma vulvar con diferenciación simplástica. CONCLUSIONES: En contraposición con sus homólogos uterinos, la localización vaginal del leiomioma es excepcional. Si bien hasta ahora no ha podido demostrarse la efectividad de la biopsia preoperatoria se aconseja su toma porque podría tratarse de una masa de características malignas, lo que modificaría el tratamiento y su urgencia. La actitud quirúrgica es, quizá, la más acertada porque permite, además de un diagnóstico anatomopatológico definitivo, un tratamiento curativo. Se propone la escisión completa, mediante una incisión elipsoidal en la piel y asegurar la extirpación completa de la pseudocápsula.

Abstract BACKGROUND: Leiomyomas are benign tumors that originate in smooth muscle fibers. Most leiomyomas of the female genital tract are located in the uterus. Extrauterine localization is exceptional; the incidence of vulvar leiomyoma is 0.07%. These smooth muscle tumors are usually painless, slow growing and can occur in women of any age. OBJECTIVE: To report a case of vulvar leiomyoma that because of its low incidence and clinical similarity to other lesions, such as Bartholin's gland cyst, may lead to an initial misdiagnosis. In addition, a review of the literature should be carried out in order to contribute to its diagnosis and treatment. CLINICAL CASE: A 52-year-old patient with a vulvar mass of years of evolution and an initial misdiagnosis of Bartholin's gland cyst. The patient was operated by surgical excision and subsequent histopathological study. The definitive diagnosis was vulvar leiomyoma with symplastic differentiation. CONCLUSIONS: In contrast to its uterine counterparts, the vaginal location of leiomyoma is exceptional. Although the effectiveness of a preoperative biopsy has not been demonstrated so far, it is advisable to take a biopsy because it could be a mass with malignant characteristics, which would change the treatment and its urgency. The surgical approach is perhaps the most appropriate because it allows, in addition to a definitive anatomopathological diagnosis, a curative treatment. Complete excision is proposed, by means of an ellipsoidal incision in the skin and ensuring complete excision of the pseudocapsule.

Úlcera vulvar aguda de Lipschütz / Acute vulvar ulcer of Lipschütz

RESUMEN La úlcera de Lipschütz es una entidad poco frecuente e infradiagnosticada. Se presenta el caso de una paciente de 24 años sin antecedente de contacto sexual que consultó por aparición súbita de úlceras vulvares dolorosas, en el contexto de un cuadro pseudogripal. Se discuten los principales diagnósticos diferenciales, dado que es una enfermedad no relacionada con enfermedades de transmisión sexual y poco reconocida por los profesionales de la salud, que precisa de manejo conservador.

ABSTRACT Lipschütz ulcer is a rare underdiagnosed entity. We present the case of a 24-year-old patient without history of sexual contact who consulted for sudden occurrence of painful vulvar ulcers, in the context of flu-like symptoms. The main differential diagnoses are discussed, as it is a disease unrelated to sexually transmitted diseases and little recognized by health professionals, which requires conservative management.

Abrikossoff’s tumor: report of a rare tumor and its unusual vulvar location / Tumor de Abrikossoff: relato de tumor raro e de localização incomum na vulva

The first report of granulosa cell tumor occurred in 1926, by Abrikossoff, after whom it was named “Abrikossoff’s tumor”. It is a benign, uncommon neoplasm, most frequently observed in the head, neck and tongue, being found in the vulva only in 6%-7% of the cases. Its histogenesis is uncertain, probably linked to Schwann cells. The treatment is surgical, with good prognosis. Relapses may occur, and there are descriptions of malignant transformation in the literature. The objective of this paper is to describe a case of granular cell tumor located in the vulva.

O primeiro relato do tumor de células granulosas ocorreu em 1926, por Abrikossoff, nome que deu origem à denominação “tumor de Abrikossoff”. Trata-se de neoplasia benigna, incomum, observada mais frequentemente na cabeça, no pescoço e na língua, sendo encontrado na vulva em apenas 6%-7% dos casos. Sua histogênese é incerta, provavelmente ligada às células de Schwann. O tratamento é cirúrgico, com bom prognóstico. Podem ocorrer recidivas, e existem descrições de malignização na literatura. O objetivo deste trabalho é descrever um caso de tumor de células granulares localizado na vulva.

Úlcera genital aguda de Lipschütz: caso clínico / Lipschütz acute genital ulcer: case report

La úlcera genital aguda (UGA) o úlcera de Lipschütz constituye una infrecuente entidad clínica caracterizada por la aparición de úlceras genitales en niñas y adolescentes que no han iniciado su actividad sexual. El cuadro es de inicio agudo, con formación de úlceras dolorosas habitualmente precedidas en su aparición por manifestaciones sistémicas tales como fiebre, cefalea, astenia, adinamia, mialgias y adenopatías inguinales, y donde el estudio microbiológico de la lesión descarta un posible origen infeccioso. A pesar de presentar un cuadro clínico característico, esta enfermedad constituye una entidad poco conocida y por tanto subdiagnosticada, motivo por el cual presentamos el caso de una paciente de 10 años con diagnóstico de UGA realizado en el Departamento de Dermatología de la Pontificia Universidad Católica de Chile.

Acute genital ulcer (AGU) or Lipschütz ulcer is a rare clinical entity characterized by the appearance of genital ulcers in children and adolescents who have not initiated sexual activity. The picture is of acute onset, with formation of painful ulcers on their occurrence usually preceded by systemic manifestations such as fever, headache, fatigue, weakness, muscle pain and inguinal lymphadenopathy, and where the microbiological study of injury rule out a possible infectious origin. Despite presenting a characteristic clinical picture, this disease is a little known entity and under diagnosed, we present the case of a 10 years old girl diagnosed with UGA conducted at the Department of Dermatology, Catholic University of Chile.

The impact of the latest classification system of benign vulvar diseases on the management of women with chronic vulvar pruritus.

Background: The management of women with chronic benign vulvar dermatoses has been one of the most difficult and challenging aspects of women's healthcare for a long time. Aim: Our aim was to compare the ability to approach the specific diagnosis of nonneoplastic and noninfectious vulva diseases, between the new classification system and the old classification system. Methods: One hundred women with chronic vulvar pruritus were included in the study. After detailed examination of the vulva, all visible lesions were biopsied, with normal skin included. All specimens was sent for dermatopathology and examined simultaneously under a binocular microscope by two pathologists. Specific diagnosis if possible and histopathological findings were classified according to both the 1987 and 2006 International Society for the Study of Vulvar Diseases (ISSVD) classifications. The ratios that were able to be approached on the specific diagnosis, with the aid the two classification systems, were compared. Results: Specific clinical diagnosis by both pathological and after using clinicopathological correlation was possible in 69 out of 91 patients (75.8%) according to the 1987 ISSVD classification, and in 81 out of 91 patients (89.0%) according to the ISSVD 2006 classification system. The difference in the clinical diagnosis ratios between the two classification systems was statistically significant ( P < 0.05). In a subgroup of women without specific diagnosis at the time of pathological examination, clinical diagnosis was made in 28 out of 50 women (56%) after using the clinicopathological correlation according to the ISSVD 1987 classification, whereas, specific diagnosis was made in 39 out of 49 (79.6%) women after using the clinicopathological correlation according to the ISSVD 2006 classification. The difference was statistically significant in terms of the ratio of the ability to achieve a specific diagnosis ( P < 0.01). Conclusion: ISSVD 2006 classification of nonneoplastic and noninfectious vulvar disease is more useful than the former classification, in terms of approaching the specific diagnosis of vulvar dermatoses.

Tiña vulvar: análisis histopatológico de un caso / Tinea of the vulva: a histopathological case analysis

Introducción: la tiña vulvar es una entidad de difícil diagnóstico clínico que puede también pasar desapercibida en la biopsia. Objetivo: presentar el caso de una mujer con esta entidad, diagnosticado por la biopsia, y hacer comentarios relevantes sobre el tema con énfasis en el diagnóstico histopatológico. Metodología: se trata de una paciente sometida a biopsia por prurito vulvar persistente. No se anotan otros datos de historia clínica, incluida la edad. En la biopsia se observó una dermatitis psoriasiforme liquenificada, con paraqueratosis y grupos de neutrófilos en la capa córnea y con tapones córneos infundibulares; en la dermis superficial se apreciaban papilas profundas con algunos linfocitos y fibrosis vertical. Se sospechó el diagnóstico de psoriasis pero la coloración de PAS (coloración de ácido peryódico de Schiff), solicitada por la presencia de neutrófilos intracórneos, demostró abundantes hifas en un infundíbulo confirmándose el diagnóstico de tiña vulvar. Conclusiones: la entidad demostrada es rara y tiene como uno de sus patrones histopatológicos la presencia de una dermatitis psoriasiforme y liquenificada. El hallazgo de neutrófilos intracórneos siempre debe hacer sospechar la presencia de una tiña. La coloración de PAS es una manera fácil de confirmar el diagnóstico. En la literatura revisada se constata que la tiña vulvar es una extensión de la tiña cruris, producida con mayor frecuencia por Trichophyton rubrum. Los diagnósticos diferenciales incluyen candidiasis, psoriasis y dermatitis de contacto.

Introduction: tinea of the vulva is a difficult clinical entity which may well go unnoticed in a biopsy. Objective: presenting the case of a woman suffering this disease, diagnosed by biopsy, and making some comments emphasising the value of histopathological diagnosis. Methodology: a vulvar biopsy was taken as the patient had complained of persistent pruritis. No clinical history was obtained. The biopsy revealed lichenified psoriasiform dermatitis, parakeratosis and groups of neutrophils in the horny layer and infundibulum; deep dermal papillae, lymphocytes and vertical fibrosis were visible in the dermis. Although such findings are also seen in psoriasis, PAS staining was done due to the presence of neutrophils, showing abundant infundibular hyphae, thereby confirming the diagnosis of tinea of the vulva. Conclusions: this rare entity has a lichenified psoriasiform histological pattern. The finding of neutrophils in the horny layer must always lead to suspecting the presence of tinea. PAS staining is an easy way to confirm such diagnosis. Reviewing the literature revealed that tinea of the vulva is an extension of tinea cruris, most frequently caused by Trichophyton rubrum. Differential diagnosis includes candidiasis, psoriasis, and contact dermatitis.
