A case of reactive eccrine syringofibroadenoma

Adnexal neoplasms of the eye

Adnexal neoplasms of the eyelid encompass a wide variety of benign and malignant tumors of sebaceous, follicular, and sweat gland origin. Due to the specialized structures of the eyelid, these neoplasms present differently when compared with those of other locations. Although most dermatologists and ophthalmologists are familiar with the commonly reported adnexal tumors of the eyelid, such as hidrocystoma, pilomatrixoma, and sebaceous carcinoma, many other adnexal neoplasms have been reported at this unique anatomic site. Accurate and timely identification of these neoplasms is essential, as alterations of eyelid anatomy and function can have a negative impact on eye health, vision, and quality of life. We review the clinical and histopathologic features of common and rare eyelid adnexal neoplasms and discuss proposed treatment options.

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.

Eccrine Syringofibroadenoma of the Heel: A Case Report

Eccrine syringofibroadenoma is a rare, benign tumor of eccrine ductal differentiation, typically presenting in the extremities. Herein we report a case of a 77-year-old man with pain in the lateral midfoot and the presence of an eccrine syringofibroadenoma lesion in the lateral heel. On surgical excision of the lesion, the foot pain promptly resolved, and at the most recent follow-up visit, the patient remained pain free.

Eccrine Syringofibroadenoma in a Patient with Long-Standing Exfoliative Dermatitis

Eccrine syringofibroadenoma (ESFA) is a rare benign cutaneous adnexal lesion characterized by a hyperplastic epithelium and eccrine ductal differentiation. In the present case, a 73-year-old Korean male presented with symmetrical numerous widespread, pinkish nodules with a cobblestone appearance over both legs for 2 years. He had a history of generalized erythematous scaly patches over his entire body for 20 years. On histopathologic findings, diagnosis of ESFA was confirmed. Our unusual and interesting case emphasizes the first report described one case in which multiple cobblestone like ESFAs arising from long-standing exfoliative dermatitis.

Multiple Eccrine Syringofibroadenoma of Mascaro of the Lower Extremity

Eccrine syringofibroadenoma (ESFA) is a rare benign lesion of ductal and secretory differentiation exhibiting multiple cutaneous polymorphic presentations with an unknown etiology. We present a case of ESFA that uniquely exhibited large, thick, verrucous-like hyperplastic growths as well as superficial shiny mosaic plaques and deep ulcerations in three different anatomical locations in the same patient. The diagnosis of ESFA was confirmed histologically after biopsies were performed on all of the affected areas. In addition to a case report and literature review, we also present classification, clinical, and histologic aspects of ESFA.

Syringometaplasia: variants and underlying mechanisms

Syringometaplasia is an adaptive, benign, metaplastic cellular process that affects the eccrine ducts and glands in response to a variety of physiological or pathological stimuli. Different subtypes of syringometaplasia have been described, including the squamous, mucinous, and adenomatous types. These metaplastic changes have been reported in association with chemotherapeutic agents, as well as with a variety of skin disorders including multiple infectious, neoplastic, and inflammatory skin diseases. In this review, we attempt to shed light on the different patterns of syringometaplasia, its pathogenesis, the plethora of skin conditions in which it may be observed, and the differential diagnoses that should be considered.

Reactive Eccrine Syringofibroadenomatosis Presenting as Bilateral Plantar Hyperkeratosis

Eccrine syringofibroadenoma (ESFA) is a rare cutaneous tumor with eccrine differentiation with varied clinical manifestations. We report a case of reactive eccrine syringofibroadenomatosis associated with chronic bilateral plantar ulcers in a patient with diabetes mellitus presenting as plantar hyperkeratosis and verrucous growth at margins.
