1/10. 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 = 1keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
2/10. The efficacy of electrosurgery and excision in treating patients with multiple apocrine hidrocystomas.BACKGROUND: Apocrine hidrocystomas are adenomatous cystic proliferations of the apocrine glands. They typically occur as solitary lesions, though rarely may occur as multiple lesions. Management of multiple hidrocystomas can be difficult, particularly if they are large. Surgical modalities may be required for effective therapy. OBJECTIVE: To compare the results of electrosurgery and excision in treating multiple apocrine hidrocystomas. methods: A 50-year-old man presented with multiple apocrine hidrocystomas ranging in size from 1 to 12 mm. The lesions were located over the periorbital skin, cheeks, and pinnae. Excision and electrodessication were utilized for therapy. At a 1-year follow-up, the patient was evaluated for recurrences and cosmetic result. RESULTS: There were no recurrences until 1 year after surgery. In the areas treated with electrodessication, no visible scars were identified. In the areas treated with excision, localized scars were observed. CONCLUSIONS: Both electrodessiation and excision are effective therapies for multiple apocrine hidrocystomas. We suggest that tumors less than 1 cm be treated with electrodessication and lesions greater than 1 cm with excision.- - - - - - - - - - ranking = 0.003374555172433keywords = gland (Clic here for more details about this article) |
3/10. fibroadenoma of the eyelid.Extramammary fibroadenomas have been previously reported to mainly occur in the anogenital region, arising from mammary-like glands. The present report describes a 45-year-old woman who presented with a fibroadenoma of her eyelid that was associated with a cystadenoma. To our knowledge, this is the first case report of a fibroadenoma of the eyelid. The differential diagnosis and histogenesis of this lesion are discussed, and the literature pertaining to cutaneous fibroadenomas arising outside the breast is reviewed.- - - - - - - - - - ranking = 0.003374555172433keywords = gland (Clic here for more details about this article) |
4/10. Rectal hidrocystoma.We describe the endorectal sonographic and magnetic resonance (MR) imaging findings of a hidrocystoma of the rectal wall, a tumor that arises in sweat glands and may occur in a perianal location. To our knowledge, occurrence in the rectum has not been reported previously. The unusual appearance of a solid lesion with a central fluid-filled cavity may suggest the diagnosis of a hidrocystoma.- - - - - - - - - - ranking = 1keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
5/10. Multiple eccrine hidrocystomas: a new therapeutic option with botulinum toxin.BACKGROUND: Multiple eccrine hidrocystomas are benign cystic lesions that are associated with a chronic course and seasonal variability. Even though in the literature it is presented as a very infrequent pathology, we think this is more a lack of knowledge of the existence of said pathology and the fact that patients confuse it with comedo. OBJECTIVE: To treat multiple eccrine hidrocystomas of the face. RESULTS: We present a case of multiple eccrine hidrocystomas of the face in a cook man. hidrocystoma is a benign cystic tumor of the sweat glands eccrine or apocrine. Multiple eccrine hidrocystomas are benign cystic lesions that are associated with a chronic course and seasonal variability. They appear like multiple shining small papule. Although a solitary eccrine hidrocystoma can be treated easily with surgical excision, the elimination of multiple lesions is problematic because of their number and location. CONCLUSION: The benefits of BTX-A treatment for multiple eccrine hidrocystomas include ease of application, no risk of scarring, and a good postoperative course. Because of the blockage produced by BTX-A on cholinergic terminals of the parasympathetic system that governs sweat glands secretion, it is suggested that periodic doses of BTX-A are injected in the superficial epidermis in order to treat multiple eccrine hidrocystomas.- - - - - - - - - - ranking = 2keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
6/10. Fine-needle aspiration of apocrine hidrocystoma--a potential mimic of papillary neoplasms metastasizing to the skin.We report the cytologic features of a histologically confirmed apocrine hidrocystoma as seen in fine-needle aspirates. The main cytologic features were the presence of sparse pseudopapillae with mild to moderate atypia in a background of an amorphous navy blue material reminiscent of that seen in aspirates of colloid nodules of the thyroid gland. The pseudopapillae were mistaken for malignant metastatic deposits. It is suggested that the presence of pseudopapillae in aspirates obtained from cutaneous nodules might be a clue for a tentative diagnosis of benign tumors of epidermal adnexae, with the proviso that a primary malignant tumor be ruled out first.- - - - - - - - - - ranking = 0.003374555172433keywords = gland (Clic here for more details about this article) |
7/10. Eccrine mucinous metaplasia associated with an apocrine cystadenoma.Mucinous metaplasia occurs uncommonly in cutaneous pathology, usually at specialized anatomic locations (genitalia, palms, and soles) and within restricted pathologic contexts (inflammation and trauma). Here, we report a unique case of eccrine mucinous metaplasia associated with an apocrine cystadenoma. A 13-year-old girl had an asymptomatic, 4-mm nodule on the chest. Histopathology demonstrated a typical apocrine cystadenoma in the upper and middle dermis. Adjacent to this lesion was a cluster of coiled eccrine secretory glands, of which the inner layer was almost entirely replaced by benign-appearing cells containing abundant, non-sulfated acid mucopolysaccharides. At 10 months' follow up, there was no recurrence. Our case demonstrates that, very uncommonly, mucinous metaplasia may be associated with a pathogenetically separate, adjacent proliferative adenomatous lesion, in this instance, an apocrine cystadenoma.- - - - - - - - - - ranking = 0.003374555172433keywords = gland (Clic here for more details about this article) |
8/10. Treatment of multiple apocrine hidrocystomas with trichloroacetic acid.The apocrine hidrocystoma is a benign adenomatous cystic proliferation derived from apocrine glands, which frequently occurs in periocular tissues. These cystadenomas may occur bilaterally, in multiple disfiguring confluent groups on both the upper and lower lids. Although these lesions have been treated successfully with meticulous surgical extirpation and electrosurgery, this report describes the successful treatment of two patients, each with multiple large (>7 mm) periocular apocrine hidrocystomas by either chemical ablation of the cystic epithelium with trichloroacetic acid (TCA) or surgical excision. Examination of the cysts at 1, 3, and 6 months after TCA treatment revealed well-healed lesions without cyst recurrence. Most of the TCA-treated cysts resolved completely, without leaving any trace to clinical examination. Treatment of cysts with TCA was technically simpler and much less time-consuming than surgical excision. The treatment of large apocrine hidrocystomas with TCA is an effective and expeditious method of treating these disfiguring and recalcitrant lesions.- - - - - - - - - - ranking = 0.003374555172433keywords = gland (Clic here for more details about this article) |
9/10. Multiple hidrocystomas.Apocrine hidrocystoma is a cyst from the secretory portion of the apocrine sweat gland and tends to occur as a solitary facial lesion. We report a 66-year-old woman with multiple, cystic lesions on her face. Histopathology revealed cystic spaces lined by a row of secretory cells showing decapitation secretion. We emphasize the multiple character of the case and discuss its distinction from so-called eccrine hidrocystomas.- - - - - - - - - - ranking = 0.090388307382894keywords = sweat, gland (Clic here for more details about this article) |
10/10. Apocrine hidrocystoma of the finger.An apocrine hidrocystoma occurring on the finger of a 55-year-old man is reported. The lesion presented as a solitary, painless cystic nodule on the dorsal aspect of the middle phalanx of the index finger. Apocrine hidrocystoma is a benign tumour developed from apocrine sweat glands, but the location of the lesion was, however, not consistent with reported locations of apocrine glands in the adult.- - - - - - - - - - ranking = 1.0033745551724keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
