Hidradenoma nodular maligno / Malignant Nodular Hidradenoma

Introducción: El hidradenoma nodular maligno es un tumor maligno de glándula sudorípara ecrinas, poco común, considerada una lesión de diferenciación anexial ecrinas, que generalmente surge de nuevo, aunque se han descrito unos pocos casos surgidos sobre un hidradenoma nodular. Es decir, representa la contrapartida maligna del hidradenoma nodular. Objetivo: Dar a conocer la presentación de un caso, dada la inusual aparición de esta entidad, con revisión de los criterios para su diagnóstico. Caso clínico: Se informa el caso de un hombre de 74 años de edad con una neo formación en la región parietal derecha del cuero cabelludo. Conclusiones: Debemos pensar en un hidradenoma nodular maligno ante un tumor solitario, firme o fluctuante, infrecuente en el cuero cabelludo, con curso agresivo, recurrencias y metástasis ganglionares y confirmar su diagnóstico con el estudio inmunohistoquímico(AU)

Introduction: Malignant nodular hidradenoma is a rare malignant eccrine sweat gland tumor considered a lesion of eccrine adnexal differentiation, which usually arises again, although a few arising cases on nodular hidradenoma have been described. In other words, it represents the malignant counterpart of nodular hidradenoma. Objective: To report a case, given the unusual occurrence of this entity, with a review of the criteria for its diagnosis. Case report: We report the case of a 74-year-old man with a neoformation in the right parietal region of the scalp. Conclusions: We should consider a malignant nodular hidradenoma when faced with a solitary, firm or fluctuant tumor, rare in the scalp, with aggressive evolution, recurrences and lymph node metastasis, and confirm its diagnosis with immunohistochemical study(AU)

Síndrome de Brooke-Spiegler asociado a carcinoma basocelular: reporte de caso / Brooke-Spiegler syndrome associated with basal cell carcinoma: case report

El síndrome de Brooke-Spiegler (SBS) es una entidad rara, autosómica dominante, que ocurre por mutaciones del gen CYLD, el cual funciona como supresor de tumores. Se presenta el caso de una mujer de 50 años de edad, con historia de aparición de lesiones características de tricoepiteliomas que predominaban en nariz, región interciliar y mentón, que iniciaron desde los 14 años de edad. Desde hace 5 años refiere aumento del tamaño de lesiones en alas nasales, y una lesión en punta nasal de 2 años de evolución. Al realizarse una correlación clínica e histológica, asociada a los antecedentes familiares de la madre y hermano de la paciente, se concluyó que el cuadro clínico era compatible con tricoepitelioma múltiple familiar, una variante especial del SBS, en este caso asociado a carcinoma basocelular, que aunque no es un hallazgo común, se ha visto que se puede presentar en esta enfermedad. El diagnóstico preciso de SBS requiere de una correlación clínico-histológica, y se debe hacer un seguimiento clínico cercano para detectar cambios en las lesiones en piel, que puedan indicar una transformación maligna

Brooke-Spiegler syndrome (BSS) is a rare autosomal dominant condition that occurs due to mutations in the CYLD gene, which functions as a tumor suppressor gene. The case of a 50-year-old woman with a history of characteristic trichoepitheliomas predominantly in the nose, glabella and chin that began at 14 years of age is presented. She reports an increase in the size of the nasal ala lesions for the past 5 years, and the appearance of a new lesion in the nasal tip 2 years ago. When performing a clinical and histological correlation, associated with family history in both the mother and brother, it was concluded that the diagnosis was compatible with multiple familial trichoepithelioma, a special variant of BSS, associated in this case with basal cell carcinoma, that although not a common finding, has been seen to coexist in this disease. The diagnosis of BSS requires a clinical and histological correlation, and a close clinical follow-up must be performed to detect changes in the skin lesions that may indicate malignant transformation

Hidradenoma Papilliferum of the Anus: A Report of 2 Cases and Review of the Literature

Hidradenoma papilliferum is a rare benign cystic tumor that originates from apocrine glands or anogenital mammary glands. Here, we describe 2 cases of hidradenoma papilliferum of the anus. Two female patients aged 39 and 35 presented with perianal masses with hemorrhoids. The patients underwent hemorrhoidectomy and excision of the lesion. Histopathology confirmed the masses as hidradenoma papilliferum. The postoperative course was uneventful for both patients, and there were no recurrences after 18 and 12 months of follow-up, respectively. Proctologists should consider hidradenoma papilliferum in their differential diagnosis of benign anal tumors. Surgical excision is necessary for diagnosis and treatment of hidradenoma papilliferum.

The Reappraisal of the Slide-Swing Skin Flap: A Versatile Technique for Surgical Defects

BACKGROUND: The slide-swing skin flap is a combination of transposition and adjacent skin sliding and can be used to close large, round defects with a flap that is smaller than the primary defect to produce aesthetically good results. OBJECTIVE: To evaluate the efficacy and safety of the slide-swing skin flap for various surgical defects caused by skin tumor excisions. METHODS: This retrospective case series, which includes 33 Asian patients between the ages of 25 and 86 years, describes the slide-swing skin flap after primary excision for malignant or premalignant skin conditions. The outcomes were assessed 12 weeks after surgery using the patient and observer scar assessment scale (POSAS). RESULTS: Patients were 25 male and 8 female, and the causes of surgery were various malignant skin tumors including malignant melanoma, dermatofibrosarcoma protuberans, and malignant nodular hidradenoma. Tumors were on the lower limb in eleven patients, back in nine patients, chest in five patients, face in three patients, buttock in three patients and two patients had tumors in other locations. The mean defect size was 3.5×3.1±1.9×2.2 cm (range, 1.4×0.9~9.0×12.0 cm). The mean patient POSAS total score was 9.7±3.0 and mean patient overall opinion score was 1.8±0.7. The mean observer POSAS total score was 11.0±2.7 and mean observer overall opinion score was 1.9±0.5. All flaps survived and postoperative recoveries were uneventful. CONCLUSION: The slide-swing skin flap is highly versatile and can be used to cover various surgical defects, irrespective of size and location, with excellent functional and cosmetic results.

Perianal hidradenoma papilliferum / Hidradenoma papilífero perianal

ABSTRACT Hidradenoma papilliferum is a benign cystic tumor originated in apocrine sweat glands of the anogenital region. It is common in vulvar topography and rare in the perianal region. A well-documented case of a patient with slow-growing perianal nodulation without pain or other symptoms is reported. The histological study shows a hidradenoma papilliferum. The article reviews the topic and discusses the importance of the differential diagnosis of proctological conditions. A biopsy is mandatory in anal lesions of unusual presentation.

RESUMO O hidradenoma papilífero é um tumor cístico benigno originado nas glândulas sudoríparas apócrinas da região anogenital, sendo comum em topografia vulvar e raro na região perianal. Relata-se um caso bem documentado de paciente com nodulação perianal de crescimento lento, sem dor ou outros sintomas, cujo estudo histológico revelou se tratar de hidradenoma papilífero. O artigo revisa o tema e discute a importância do diagnóstico diferencial das afecções proctológicas, sendo a biópsia obrigatória em lesões anais de apresentação não-usual.

Localización inusual del hidradenoma papilífero / Unusual location of the papilliform hydradenoma

El hidradenoma papilífero es una tumoración benigna, rara, generalmente localizada en la región vulvar o perineal siendo la región perianal una localización poco frecuente. Su asociación con enfermedades de transmisión sexual y el carcinoma ductal es controvertida; es importante realizar el estudio histopatológico de cualquier tumoración en esta zona. Se reporta el caso de una paciente de 49 años de edad, con un nódulo en la región perianal de 2 años de evolución; el estudio histopatológico confirmó el diagnóstico de hidradenoma papilífero. (AU)

The papilliferous hidradenoma is a benign, rare tumor, usually located in the vulvar or perineal region and the perianal region is a rare site. Its association with sexually transmitted diseases and ductal carcinoma is controversial. It is important to perform the histopathological study of any tumor in this area. The case of a 49-year-old patient with a nodule in the perianal region of 2 years of evolution is reported. The histopathological study confirmed the diagnosis of papilliferous hidradenoma.

Hidradenoma poroide del pie: presentación de un caso y revisión de la literatura / Poroid hidradenoma of the foot: a case report and literature review

El hidradenoma poroide fue descrito en el año 1990, por Abenoza y Ackerman, como una de las 4 variedades morfológicas de un poroma ecrino. Sus principales características son: muy baja frecuencia, localización intradérmica y aspecto sólido-quístico. Es más prevalente en la séptima década de la vida, sin predominio por género y su localización más frecuente es en cabeza y cuello. Presentamos el caso de un hidradenoma poroide del dorso del pie (AU)

Poroid hidradenoma was described in 1990, by Abenoza and Ackerman, as one the four morphological varieties of eccrine poroma. Its main characteristics: very low frequency, intradermal location and solid- cystic appearance. It is more prevalent in the seventh decade of life, with no gender predominance and the most frequent location is in the head and neck. A case of poroid hidradenoma in the foot dorsum is reported (AU)

Axillary Nodular Hidradenoma in a 29-Month-Old Girl / 소아외과

Nodular hidradenoma was diagnosed in a 29-month-old girl on her axilla. Hidradenoma, sometimes designated as acrospiroma, is a benign sweat gland neoplasm, which mostly occurs in adults. Very few cases of hidradenoma have been documented in children in their first decade of life. This case demonstrates that when a child develops a skin nodule, nodular hidradenoma can be a diagnostic option.

A Case of Poroid Hidradenoma / 대한피부과학회지

Poroid hidradenoma is a benign tumor that is classified as a poroid neoplasm, and is so called because of its morphology, which is intermediate between the cytological features of a poroid neoplasm (poroid and cuticular cells) and the architectural features of a hidradenoma (solid and cystic areas, and tumor cells restricted to the dermis). As these tumors are cystic and superficially located, fine needle aspiration cytology has been useful, but the diagnosis relies on the histological examination. A 79-year-old woman presented with a solitary walnut-sized, soft, tender, reddish-to-bluish nodular lesion that had been enlarging steadily over a period of two years. Histopathologic examination of the cutaneous lesion showed a well-demarcated tumor composed of poroid and cuticular cells in the dermis not connected to the overlying epidermis, consistent with poroid hidradenoma. Herein, we present a rare case of poroid hidradenoma arising in an unusual location.

A Case of Apocrine Adenocarcinoma of the Upper Eyelid

PURPOSE: To report a case involving an eyelid mass that was diagnosed as apocrine carcinoma. CASE SUMMARY: A 52-year-old man visited our hospital with a recurrent mass on his right upper eyelid, which had developed 4 years prior. Initially, he received laser therapy at a dermatologic clinic to remove the mass. Two years later, the mass recurred and was excised at another clinic. At the time the patient visited our institution, the lesion had developed into multiple erythematous nodules at the margin of the right upper eyelid. The results of excisional biopsy performed under local anesthesia revealed hidradenoma papilliferum. One month after excision, recurred multiple elevated nodules were found at the margin of the excision, and thus total excision of the mass and reconstruction of the upper eyelid was performed. Biopsy confirmed that the mass was apocrine adenocarcinoma. Five months have passed since the excision and no evidence of recurrence has been observed. CONCLUSIONS: Apocrine adenocarcinoma is a malignant tumor of the sweat gland and is rarely found on the eyelid. Apocrine adenocarcinoma should be considered in the differential diagnosis of recurrent eyelid mass at the eyelid margin.
