Metastatic eccrine sweat gland carcinoma: case report

Eccrine sweat gland carcinoma is a rare malignancy of skin adnexa with potential aggressive growth and metastatic spread. We report here a case of eccrine carcinoma arising on a finger with widespread pulmonary metastasis. A brief synopsis of the pathological and clinical aspects of eccrine sweat gland carcinoma is presented and currently available therapeutic modalities are discussed.     

Histiocytoid eccrine sweat gland carcinoma of the eyelid: report of a case

This report describes the 12th documented case of histiocytoid, diffuse or signet-ring cell eccrine sweat gland carcinoma of the eyelid, a rare neoplasm that characteristically affects older men and mimics distant metastasis. Clinically, the patient was thought to have a colonic metastasis. Histologically, the neoplasm comprised sheets and cords of polygonal, eosinophilic cells, with dispersed larger, rounded single cells resembling histiocytes, and cells with cytoplasmic lumina or a signet-ring appearance. Occasional duct formation was also seen. The features were reminiscent of both the histiocytoid and lobular variants of breast carcinoma. Ultrastructurally, the presence of nonintestinal type microvilli with a length : width ratio in excess of 16 were consistent with an eccrine origin, but also raised the possibility of metastatic mesothelioma. However, a metastatic lesion was excluded by clinical and imaging investigations. There has been no recurrence 3 years after primary excision.     

Acitretin‐Responsive Ichthyosis in Chanarin–Dorfman Syndrome with a Novel Mutation in the ABHD5/CGI‐58 Gene

Chanarin–Dorfman syndrome (CDS) is a rare nonlysosomal neutral lipid storage disorder characterized by congenital ichthyosis, lipid vacuoles in leukocytes (Jordan's anomaly), and hepatomegaly. The authors herein report an 18‐month‐old boy with ichthyosis and hepatomegaly diagnosed with CDS and confirmed to have a novel c.506–3C>G mutation in the ABHD5/CGI‐58 gene. Our case also illustrates that retinoids such as acitretin could be useful in the treatment of skin manifestations in CDS even in the presence of liver derangement.

Rosai‐Dorfman disease successfully treated with thalidomide: A case report

Rosai‐Dorfman disease (RDD) is a rare disease which characterized by proliferation and overproduction of histiocytes in the lymph nodes appearing as lymphadenopathy, however, it may also occur in extranodal sites. The occurrence of unusual manifestations of the disease such as the appearance of the mass in an unusual area may increase the probability of misdiagnosis. Herein, we describe a case of RDD in an old woman with an unusual appearance of RDD in the leg that was successfully treated by thalidomide.

Malignant eccrine spiradenoma: a new case report

Malignant eccrine spiradenoma is an extremely rare skin tumor of sweat gland origin. In most cases, it arises in pre‐existing benign eccrine spiradenoma. We report an additional case of malignant eccrine spiradenoma. The present case is of a 75‐year‐old man with malignant eccrine spiradenoma developed in the right shoulder. He had a 6‐year history of a recurrent mass that was removed 2 years ago. The patient then underwent a complete excision. The gross pathologic specimen showed a large cutaneous and subcutaneous multinodular tumor, measuring 6 cm in maximal dimension. Microscopically, there were two distinct morphological components: a benign eccrine spiradenoma and a malignant eccrine spiradenoma of low grade with extensive necrosis. Different histologic patterns were observed such as cylindromatous features. Morphological differentiation in malignant eccrine spiradenoma is variable, sometimes with almost complete loss of eccrine differentiation. Extensive sampling to look for a probable previously benign component is necessary. In the other hand, malignant changes can be easily missed without adequate sampling.

Stimulated eccrine gland function in primary Sjögren''s syndrome

Sweat secretion rate, stimulated by iontophoresis of pilocarpine, was measured in 22 patients with primary Sjögren's syndrome and 22 age- and sex-matched normal control subjects. There was no significant difference in measured sweat rates (P=0·45). We conclude that the complaint of dryness of the skin in patients with Sjögren's syndrome is not due to decreased eccrine gland secretion.     

Painful eccrine spiradenoma containing nerve fibers: a case report

An eccrine spiradenoma is a rare benign tumor most often seen in the head, neck and upper trunk of young adults. Although spontaneous pain or tenderness is a typical symptom of eccrine spiradenomas, the underlying mechanism has not been fully elucidated. Here, we report the case of a 47- year-old woman who had a spiradenoma in the subcutaneous tissue of her posterior neck accompanied by agonizing pain which was triggered by pressure. Multiple nodular lesions were excised and the typical histopathological findings of spiradenoma were seen. The histopathological architecture of a disorganized nerve fiber encasing the tumor nodules appeared to correlate with the unique clinical symptom of pain.     

Metastasizing eccrine sweat gland carcinoma. Report of a case

We report a case of eccrine sweat gland carcinoma arising from the occipital region, which later metastasized to the regional lymph nodes and spread widely to the viscera. After wide local excision of the primary tumor, it recurred locally, and then metastasized presumably via regional lymph nodes. Widespread metastasis to visceral organs occurred after a ten-year latent period from the appearance of the original tumor. Histochemical and enzymatic histochemical examinations of the specimens from the original tumor and metastasized lesions obtained at autopsy disclosed the characteristics of eccrine sweat gland tumor.     

Vascular eccrine giant spiradenoma--a case report with histology and immunohistology of a rare variant of benign sweat gland tumors

Giant vascular eccrine spiradenoma (GVES) is a rare variant of benign tumors of the sweat glands, which differs from common eccrine spiradenoma in both its size and vascularity. Clinically as well as macroscopically, this intradermal or subcutaneous encapsulated tumor might be mistaken for an angiomatous lesion or thrombosis. Histological examination reveals clearly delimited "cords" showing two types of cells, prominent blood-filled cavities and extensive hemorrhages. According to immunohistochemical findings, the epithelial cells contain cytokeratin, protein S-100 and carcino-embryonal antigen (CEA). Like the endothelial cells of vessels, some of the luminal epithelial cells also bind Ulex europaeus lectin; however, they do not show factor VIII-associated antigen.
