1/299. Apocrine gland carcinoma of the axilla: review of the literature and recommendations for treatment.Apocrine gland carcinoma is a rare form of sweat gland neoplasm with a distinctive cytologic appearance. Although the region of the axilla remains the most common site for these tumors, apocrine gland carcinoma of the anogenital region, eyelid, ear, chest, wrist, lip, foot, toe, and finger have been reported. Classically, these slow-growing lesions present as painless, colorless or reddish, firm or cystic nodules. More than half of the reported patients with apocrine carcinoma had lymph node metastases at the time of diagnosis. Wide local excision is standard therapy for these lesions. A therapeutic lymph node dissection is indicated for confirmed lymph node metastases and may have a role in the setting of a large or highly aggressive tumor with narrow surgical margins. Although apocrine gland carcinoma responds poorly to chemotherapy, adjuvant radiotherapy may be used in advanced local or regional disease. The authors describe a 69-year-old man with a large recurrent apocrine gland carcinoma of the axilla treated with en bloc excision with axillary dissection and offer a pertinent review of the English literature and recommendations for treatment.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/299. Extensive naevoid eccrine spiradenoma.We describe a 19-year-old girl with a painful naevoid eccrine spiradenoma affecting the right side of the body. This represents an extremely rare variant of this benign eccrine sweat gland tumour, and is the most extensive lesion described in the U.K. to date.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
3/299. Pigmented hidrocystoma of the eccrine secretory coil in the vulva: clinicopathologic, immunohistochemical and ultrastructural studies.A case of pigmented hidrocystoma of eccrine secretory coil is presented. A 47-year-old woman had developed a bluish black small nodule in the anterior portion of the labium minor a few years before entry. Microscopically, the cyst was lined by eosinophilic columnar epithelium with abundant brownish granules. There was a vague suggestion of decapitation secretion focally in the epithelial layer of cuboidal cells. This layer expressed distinct reactivity against CA19-9 with no reactivity for human milk fat globule-1 (HMFG-1). These features demonstrated that the cyst was not of apocrine nature but of eccrine derivation. In addition, positive immunoreaction for cytokeratin (CK)7, CK8 and CK19 defined the cyst as originating from the secretory coil of the sweat gland. Ultrastructurally, melanosomes in various stages were identified in most of the epithelial cells. These findings suggest that the present case was a hidrocystoma of eccrine secretory coil with abnormal melanin accumulation.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
4/299. Primary eyelid mucinous adenocarcinoma of eccrine origin.To report a case of mucinous adenocarcinoma of the eyelid. A 70-year-old man presented with a lesion of his lower left eyelid, which had been growing over the past few years. An excisional biopsy was performed. The lesion was incompletely excised and recurrence at the excision site was observed at a 3-month follow-up visit. A histopathological examination of the excised specimen showed it to be a mucinous adenocarcinoma of eccrine origin. Primary mucinous adenocarcinoma of the eye lid is a rare malignant sweat gland tumor with a high incidence of local recurrence. It has to be differentiated from other adenocarcinomas which may rarely metastasize to the skin.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
5/299. A rare case of atypical eccrine acrospiroma of the scalp and a literature review.Acrospiromas are rare cutaneous lesions of eccrine sweat gland origin that are found most commonly on the extremities. The authors present a rare case of an atypical eccrine acrospiroma arising in the scalp, and a review of the literature.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
6/299. bone marrow relapse in primary mucinous carcinoma of skin.Primary mucinous carcinoma of skin is a rare adnexal tumor arising from the eccrine sweat gland. The tumors grow slowly and have low rates of local recurrence and rare chances of distant metastasis. The authors report a 70-year-old man with primary mucinous skin carcinoma who had a relapse in bone marrow 19 months after initial treatment.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
7/299. Sweat gland adenoma with predominant myoepithelial differentiated features: case report and immunohistochemical study.A 56-year-old man presented with a subcutaneous mass adjacent to the sternoclavicular joint region, which had predominant spindle-shaped myoepithelial cells and a small number of tubular or trabecular epithelial cells that resembled eccrine differentiation under a light microscope. Immunohistochemical studies showed positive staining for muscle-specific actin and vimentin in the myoepithelial cells, but staining was negative for S-100 protein and keratin. The tubular and trabecular epithelial cells stained positively for keratin, EMA and CEA. We believe that this rare tumor had the potential for biphasic differentiation and should be differentiated from other biphasic differentiated or mixed tumors in this site. Immunohistochemical staining was useful for diagnosis and differential diagnosis.- - - - - - - - - - ranking = 0.44444444444444keywords = gland (Clic here for more details about this article) |
8/299. Metastasizing porocarcinoma of the head with lethal outcome.Porocarcinoma is a very rare malignant tumor arising from the duct of eccrine sweat glands. Its prognosis is variable.

9/299. Intracranial extension of an eccrine porocarcinoma. Case report and review of the literature.eccrine porocarcinoma is a rare malignant tumor of the true sweat gland. It commonly presents in the lower extremities with lymphatic metastasis. The authors describe the clinical presentation, radiographic evidence, operative discoveries, and pathological findings in a patient with an eccrine porocarcinoma involving the soft tissue of the occiput, which had eroded through the cranium. A review of the literature failed to reveal any other such case. The discussion includes the epidemiology, pathogenesis, treatment, and outcome of eccrine porocarcinomas. The six reported cases of scalp eccrine tumors are reviewed.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
10/299. Paget's disease of the vulva associated with local adenocarcinoma and previous breast adenocarcinoma: report of two cases.We report two women in whom vulval Paget's disease occurred in association with local adenocarcinoma and previous breast adenocarcinoma. The first patient presented at the age of 83 years with moist erythematous changes over the perineum and an indurated area near the anus. biopsy of the indurated area showed Paget's cells throughout the epidermis and, below, adenocarcinoma infiltrating the dermis. Ten years previously, she had undergone a left mastectomy for infiltrating ductal carcinoma of the breast. The second patient was diagnosed as having Paget's disease at the age of 74 years. A vulval biopsy showed Paget's cells in the epidermis but, in addition, there were changes suggestive of adenocarcinoma of the sweat glands. Her symptoms of vulval itching had started at the age of 45 years and had led to a simple vulvectomy at the age of 57 years. Retrospective review of this vulvectomy specimen showed Paget's disease. She had also previously been treated for infiltrating ductal adenocarcinoma of the breast and adenocarcinoma of the rectum. The management of Paget's disease is difficult because of its high recurrence rate and, as illustrated by our two cases, treatment is difficult if the patients are elderly and in poor general health.- - - - - - - - - - ranking = 0.11111111111111keywords = gland (Clic here for more details about this article) |
