ABSTRACT
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)

RESUMEN El Hidradenoma nodular maligno o Hidradenocarcinoma es un tumor poco frecuente, derivado de las glándulas sudoríparas ecrinas. Puede surgir de novo o por la transformación de su contraparte benigna. Estos tumores son de crecimiento lento, comportamiento agresivo, con alta incidencia de recurrencias y posibilidad de metástasis. Su prevalencia es en la población adulta, y su pronóstico, incierto. El tratamiento de elección de estos tumores es la escisión quirúrgica con márgenes amplios.
ABSTRACT The Malignant nodular Hydradenoma or Hydradenocarcinoma is a rare tumor, derived from the eccrine sweat glands, may arise de novo or by the transformation of its benign counterpart. These tumors are slow growing, aggressive behavior, with a high incidence of recurrences and the possibility of metastasis; its prevalence being in the adult population, and its prognosis is uncertain. The treatment of choice for these tumors is surgical excision with wide margins.
ABSTRACT
Malignant Nodular hidradenoma is an extremely rare aggressive tumour originating from eccrine sweat glands with an incidence of <.001%. So far less than 80 cases have been reported in the literature. It’s known for its local recurrence (50%) and metastasis (60%) and hence early diagnosis and radical treatment is mandatory. But differentiating it from its benign counterparts and other skin tumour mimics is challenging, due to its histopathological similarity & lack of diagnostic immunomarkers. Authors report a case of 65-year-old female who presented with a short 4-month history of rapidly growing ulceroproliferative growth in the right inguinal region with bilateral inguinal node enlargement, associated with pain and discharge. Wedge biopsy of left inguinal lymph node showed malignant cutaneous adnexal tumour deposits, which after excision was typed as malignant nodular hidradenoma. It was confirmed with immunohistochemistry. Patient presented with recurrence 8 months after excision.
ABSTRACT
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.

Hidradenoma papilliferum is a rare cutaneous adnexal tumour of middle aged females arising mainly in the apocrine sweat glands of perianal and genital region. Ectopic forms of this entity have been described with majority of them occurring on the head and neck region. We report a case of 16 years young male who presented with two small, well circumscribed, greyish-brown, firm, nodules on his left upper and lower eyelid. A clinical impression of basal cell carcinoma was assumed but on histopathological examination it was diagnosed as hidradenoma papilliferum of eyelid. Immunohistochemistry was performed to support the diagnosis due to its unusual clinical presentation. To the best of our knowledge, only six cases in the upper eyelid and one case in the lower eyelid have been reported in the English literature. This is the first case report of hidradenoma papilliferum involving both upper and lower left eyelid in an adolescent boy.
ABSTRACT
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.

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.

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.

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.

El hidradenoma papilífero es un tumor infrecuente que ocurre casi de manera exclusiva en la región anogenital de las mujeres, sin embargo se han descrito casos de hidradenomas papilíferos ectópicos. Las lesiones generalmente son asintomóticas de crecimiento lento, eritematosas, firmes, y se presentan como un nódulo bien delimitado. Reportamos tres casos de hidradedoma papilífero en región vulvar, diagnosticados entre 2009 y 2010 en el Hospital Universitario de Caracas. En los tres casos se presente una lesión única, nodular, en labio mayor, con diámetro < 10 mm, renitente, nacarada, no pruriginosa. Hasta la actualidad se ha reportado solo un caso en laliteratura venezolana
Hidradenoma papilliferum is a rare tumor that occurs almost exclusively in the anogenital region of women, however has been reports ectopic hidradenoma papilliferum. The lesions are usually asymptomatic, slow-growing, erythematous, firm, and are presented as awell-defined nodule. We report three cases of vulvar hidradenoma papillifirum, diagnosed between 2009 and 2010 at the Hospital Universitario de Caracas. In all three cases was presented as a single, nodular lesion in labia major with a diameter < 10mm, firm, pearly, not itchy. Until now it has been reported only one case in Venezuelan literature

BACKGROUND: Poroid neoplasms consist of classic poroma, hidroacanthoma simplex, dermal duct tumor, and poroid hidradenoma. Poroid neoplasms are not rare tumors in dermatology. However, studies of the clinicopathologic characteristics of poroid neoplasms in Korea are very limited. OBJECTIVE: To investigate the clinicopathologic characteristics of poroid neoplasms in Korea. METHODS: The clinicopathologic characteristics of forty three cases of poroid neoplasms were retrospectively analyzed. RESULTS: Poroid neoplasms were diagnosed mostly in the sixth decade, without sex predominance. The most common site was the lower extremities, followed by the head & neck, the trunk, the sole, the palm, and the upper extremities. All cases were observed as a solitary lesion. Papule or nodule shape, verrucous surface, and erythmatous color were most common characteristics of poroid neoplasms. The two cases showed sebaceous differentiation. Some cases showed melanin pigmentations in the lesions or perilesional basal layer. CONCLUSION: Our study will be a resourceful data of poroid neoplasms for dermatologists and pathologists.

Hidradenoma papilliferum (HP) is a benign neoplasm arising from mammary-like glands which typically involves the dermal layer of the female anogenital area. The prognosis for HP is good. Recurrence is unusual and is typically attributed to incomplete excision of the primary tumor. Malignant transformation is rare and HP of the breast has not yet been reported. Ectopic HP is usually solitary, small, and asymptomatic. It appears as a well-circumscribed, complex cystic mass in the dermis on ultrasound. We present a case of HP arising from the axillary tail of the breast.

PURPOSE: To report the presentation and management of an atypical and advanced case of nodular hidradenoma of the eyelid with ptosis. CASE SUMMARY: A 64-year-old woman who presented with a palpable growing nodular mass and ptosis was tested with marginal reflex distance 1 as right eye 1 mm, left eye -1.5 mm and levator function test as 12 mm and 10 mm, respectively during a hospital visit. The patient was tentatively diagnosed with eyelid adnexal tumor with mechanical ptosis and was managed by surgical excision of the lesion. Histology confirmed hidradenoma. CONCLUSIONS: Hidradenomas are benign adnexal tumors originating from the eccrine gland and rarely detectable in the eyelid. However, rudimentary glandular structures can be a possible tumor source. Nodular hidradenoma should be considered in the differential diagnosis of adnexal masses and such lesions may cause significant functional and cosmetic morbidity despite their histologically benign nature.

Hidradenoma papilliferum is a rare benign neoplasm that usually occurs in the female anogenital area. We present a 43-year-old female with a non-anogenital (ectopic) hidradenoma papilliferum on her nose. The patient had had a skin-colored subcutaneous nodule on her nose for 7 years. The histopathological findings showed variously shaped cystic spaces in the tumor. And the lumina were surrounded by a single or double layer of cell which showed decapitation secretion. In the English dermatological literature, only one case of ectopic hidradenoma papilliferum arising in nasal skin has been reported. Hence we suggest hidradenoma papilliferum occurring on the nasal skin is a peculiar and interesting event.

The role of ultrasound (US) is limited in the pathologic diagnosis of soft tissue tumors. It is possible to predict the pathologic results of some common soft tissue tumors with typical US features. We report the US and pathologic findings of three angiolipomas, one nodular hidradenoma, and one benign myofibroblastic tumor, which are uncommon soft tissue tumors with characteristic US findings.

Hidradenoma papilliferum is a benign, cystic, papillary tumor that occurs almost exclusively in women on the skin of the anogenital region and this is usually a slow-growing cystic dermal mass that can be either asymptomatic or it can ulcerate and bleed, and it represents an adenoma with apocrine differentiation. Nonanogenital (ectopic) hidradenoma papilliferum is rare. We present here a case of hidradenoma papilliferum in a 52-year old male with an erythematous to brownish nodule on the left cheek and the lesion had the typical histopathological findings of hidradenoma papilliferum.

Clear cell hidradenoma (CCH) is a relatively rare benign tumor that shows differentiation toward the structure of an eccrine sweat gland. The tumor masses are composed of solid areas and tubular lamina. Cystic spaces are often present and on rare occasions they can be of considerable size. The cystic variant of CCH is referred as solid cystic hidradenoma. We present a case of cystic clear cell hidradenoma that occurred on the abdomen in a 42-year-old man. The tumor contained a solid tumor of CCH encircled by a large cystic space, and the cystic space was lined by two to four layers of epithelium.
