A Case of Eccrine Spiradenoma in a Patient with Neurofibromatosis

Neurofibromatosis is a systemic hereditary disorder with varied manifestations in bone, soft tissue, the nervous system and skin. Cutaneous manifestations of neurofibromatosis are characterized by café-au-lait macules, multiple neurofibromas, Lisch nodules and intertriginous freckling. Some benign or malignant tumors such as juvenile xanthogranuloma, pheochromocytoma, and malignant melanoma can accompany neurofibromatosis. But, in the English literature, no case of eccrine spiradenoma associated with neurofibromatosis has been reported. Eccrine spiradenoma is a benign uncommon neoplasm of skin adnexa. It presents as a painful, slow-growing and solitary nodule on the head or upper trunk. Here, we report a rare case of eccrine spiradenoma in a patient with neurofibromatosis.

Eccrine Nevus on the Neck: A Case Report and Review of the Literature

Eccrine nevus is an extremely rare benign cutaneous hamartoma that usually occurs in childhood and adolescence. It has a wide range of clinical manifestations, and histological findings reveal a proliferation of structurally normal eccrine ducts. Herein, we present a case of eccrine nevus on the neck of an 8-year-old girl. Our literature review reveals that the head and neck region is a rare anatomical location for eccrine nevus as it has a predilection for extremities. Our review also suggests that overlying skin changes are common in eccrine nevus regardless of accompanying localized hyperhidrosis.     

Eccrine Syringofibroadenoma Associated with Bowen's Disease: A Case Report and Review of the Literature

Eccrine syringofibroadenoma (ESFA) is a rare, benign adnexal neoplasm which usually manifests as a solitary nodule on the extremities of elderly patients. Few case reports have described an association between ESFA and carcinomas including squamous cell carcinoma, porocarcinoma, and basal cell carcinoma. A 66-year-old male presented with a pruritic, erythematous brownish solitary plaque with crusted and verrucous surface on the extensor side of the right thigh. The lesion developed 6 to 7 years ago, and had been growing slowly. Biopsy revealed anastomosing epithelial strands which were composed of 2 areas: the upper area consisting of dysplastic cells with prominent nucleoli and abundant mitoses, and the lower area consisting of oval and round cells, and occasionally small luminal ducts. Dysplastic cells comprised almost the entire epidermis but did not invade into the dermis. Benign syringofibroadenomatous lesion surrounded the dysplastic cells in the lowermost portion of the epidermis. Although it is still unclear whether ESFA undergoes malignant transformation or it is a reactive change to carcinoma, complete excision should be performed to prevent malignant transformation with unknown risk.     

Pediatric Segmental Eccrine Spiradenomas: A Case Report and Review of the Literature

Abstract: Eccrine spiradenoma is a rare benign adnexal tumor that usually occurs as a solitary nodule, although there are reports of multiple eccrine spiradenomas occurring in a segmental, linear, blaschkoid, or zosteriform pattern. Segmental eccrine spiradenomas have rarely been reported with onset occurring in childhood or adolescence. We describe a case of segmental eccrine spiradenomas occurring on the neck and mandible of a child.

Infectious Eccrine Hidradenitis: A Report of 3 Cases and a Review of the Literature

Neutrophilic eccrine hidradenitis (NEH) is a nonspecific clinicopathological reaction pattern, classified as a neutrophilic dermatosis, that usually develops in patients receiving chemotherapy for a hematologic malignancy. More rarely, it has been reported in association with infectious agents such as Serratia and Enterobacter species, Staphylococcus aureus, and human immunodeficiency virus.We describe 3 cases of infectious eccrine hidradenitis secondary to infection with Nocardia species, Mycobacterium chelonae, and S aureus.Histological findings revealed a dense infiltrate with perivascular and periductal neutrophils in the dermis. In the eccrine glands, there was vacuolar degeneration and necrosis of the epithelial cells.Our cases support the assertion that NEH is a characteristic cutaneous response to nonspecific stimuli. Clinical and histopathological findings of infectious and noninfectious NEH are generally indistinguishable and when NEH is suspected, the possibility of an infectious association must be investigated by skin tissue culture. In this article we also discuss differential diagnoses and review the literature.     

Poroid Hidradenoma: A Two-Case Report and Literature Review

Poroid hidradenoma (PH) is a rare benign tumor that shows differentiation of the eccrine sweat gland. It occurs mainly in adults, presenting as a 0.5 to 2 cm-sized intradermal nodule, mostly on the head, extremities, trunk and neck. We report two rare cases of PH, one on the face and the other on the heel. The first patient was a 50-year-old male who had a solitary, skin-colored nodule on his right temple for 6 months. The second patient was a 67-year-old female who presented with a solitary, bean-sized, tender nodule on her left heel for 1 year. The common histological examination finding was a well-circumscribed tumor composed of solid portions and large cystic spaces in the center. The tumor cells consisted of small, monomorphic poroid cells and large cuticular cells in both cases. To our knowledge, only few cases of PH have been reported. Herein, we report two rare cases of PHs with literature review.     

Neutrophilic Eccrine Hidradenitis: A Case Report and Review of the Literature

Neutrophilic eccrine hidradenitis (NEH) is a recently recognized dermatosis occurring in patients receiving chemotherapy for a variety of malignancies. We report the second pediatric case. An 11-year-old boy with non-Hodgkin's lymphoma developed widespread erythematous papulopustules beginning two days after receiving high-dose cytarabine (Ara-C) in preparation for a bone marrow transplant. The lesions spontaneously regressed in two weeks. Histologic examination revealed a neutrophilic infiltrate around and within the eccrine ducts and secretory coils. Bacterial, fungal, and viral cultures were negative. These findings are characteristic of NEH. The condition should be differentiated from infectious dermatoses that may require treatment.     

A Case of Eccrine Poromatosis in a Patient with a History of Chemotherapy Due to Stomach Cancer

An eccrine poroma (EP) is a benign adnexal tumor that typically presents as a single lesion. Eccrine poromatosis defined as multiple EPs is an uncommon presentation. A 54-year-old male had undergone operation for stomach cancer 10 years prior and insisted that he had also taken adjuvant chemotherapy. The patient presented with six reddish papules and nodules scattered on the trunk and extremities for 3 years. The histopathologic findings from all six lesions were consistent with EP. No local recurrence was observed after complete removal through punch biopsies. We report a rare case of eccrine poromatosis in the patient with gastric cancer, suspected of being caused by chemotherapy.     

Eccrine Angiomatous Hamartoma: A Review of Ten Cases

Background

Eccrine angiomatous hamartoma (EAH) is a rare benign nodular lesion characterized by the proliferation of eccrine and vascular structures, generally capillaries, in the middle and deep dermis. It may be congenital or appear later in childhood, but rarely arises in adulthood.

Objective

To investigate the clinicopathologic features of EAH in Korean patients.

Methods

Ten cases of EAH diagnosed at Ajou University Hospital and Gangnam Severance Hospital in Korea from 2007 to 2010 were retrospectively reviewed.

Results

The age range of patients was between 5 and 66 years with an equal number of male and female patients. Apart from two congenital cases, the onset was late, ranging from 6 months to 65 years of age. All lesions were solitary and located on the distal extremities. Nine cases appeared as a yellow-brown nodule or plaque resembling a callus. Neither hyperhidrosis nor hypertrichosis was documented. Apart from the typical histological findings of EAH, prominent mucin deposition, fat component and nerve infiltration were observed.

Conclusion

This is one of the largest single case series of EAH in the literature. Clinically, resemblance to callosities and the frequent occurrence in the adulthood were the unique features in our series.     

A Case of an Unusual Eccrine Poroma on the Left Forearm Area

A 40-year-old woman presented with an asymptomatic red to brown colored walnut-sized, dome shaped, hemorrhagic, crusted nodule on the left forearm. There was no previous history of trauma to the area. The first impression of this case was a vascular tumor or malignant lesion due to the large size and bleeding tendency. However, the final diagnosis, according to histologic and immunostaining methods, was a benign eccrine poroma that occurred on the left forearm, which is an unusual area for such a lesion. The tumor was excised and no recurrence was noted when she was examined 24 months later.     

Eccrine Porocarcinoma: A Multicenter Retrospective Study with Review of the Literatures Reported in Korea

BackgroundEccrine porocarcinoma (EPC) is a rare malignant cutaneous adnexal tumor. Other than several scattered case reports, no comprehensive review on EPC has been conducted in Korea.ObjectiveTo clinicopathologically review all EPC cases from our institutions as well as those reported in Korea.MethodsMedical records and histopathological slides of EPC cases in the skin biopsy registries of our institutions were retrospectively reviewed. Additionally, EPC cases reported in Korea before June 2019 were retrieved by searching the PubMed, KoMCI, KoreaMed, and KMbase databases.ResultsNine EPC cases from our institutions were included in the study. In addition, 27 reports of 28 patients with EPC were reported in Korea. A total of 37 patients with EPC were identified, consisting of 19 males (male:female ratio, 1.06:1; mean age at diagnosis, 65.6 years). The most common site of primary tumor was the head and neck (29.7%). Wide excision was the most common (78.4%) treatment method. Initial metastasis work-up imaging studies were performed in 18 patients (48.6%), and metastasis was confirmed in eight patients (21.6%).ConclusionEPC is a rare cutaneous carcinoma in Korea. EPC usually affects elderly patients, with no sexual predilection. Due to possible metastasis, careful diagnosis and appropriate metastasis work-ups are warranted in EPC.

Cutaneous Sparganosis: A Case Report and Literature Review

A sixty‐nine‐year‐old male patient, without a significant prior medical history, presented with a rapidly enlarging, 2 cm non‐tender nodule on the right lower eyelid. The lesion persisted in spite of an incision and drainage. Following an excision, the histology revealed a diffuse infiltrate of atypical mononuclear cells within the dermis. The cells were large, monomorphic, with irregular to convoluted nuclei, prominent nucleoli, amphophilic cytoplasm. They were very mitotically active. Immunohistochemical stains for CD45, CD3, and CD30 were strongly positive. Pancytokeratin, CD20, and ALK (Anaplastic Lymphoma Kinase fusion protein) were negative. The histopathologic diagnosis was CD30 (Ki‐1) positive anaplastic large cell lymphoma. The margin was positive for involvement by lymphoma. The lesion was re‐excised with no evidence of residual involvement by lymphoma. A primary cutaneous anaplastic large cell lymphoma was favored over systemic involvement based on the clinical presentation of a single eyelid nodule and ALK negativity. He was referred to a hematology‐oncologist for further management. Anaplastic large cell lymphoma is a distinctive type of malignant lymphoma with a relatively favorable prognosis. It frequently involves the skin, however, to the best of our knowledge, presentation of this lymphoma type as a single lesion on the eyelid is extremely rare.
