Giant vascular eccrine spiradenomas (GVESs) are a rare variant of the eccrine spiradenoma that develops from the sweat gland. It is different from the eccrine spiradenoma in its larger size and greater degree of vascularity. Bleeding and/or ulceration are common clinical features of this tumor, and are the reason why it is often clinically confused with a vascular or malignant tumor. Here, a rare case of GVES without bleeding or ulceration is reported.

Aggressive digital papillary adenoma is a rare neoplasm of eccrine sweat gland origin. We report a case of aggressive digital papillary adenoma with literature reviews. Pathogenesis of this tumor is unclear but, according to his past history, possible induction by defoliants could not be ruled out. Several immunohistochemical studies were done to confirm tumoral origin and to evaluate histological potential of malignancy.

Eccrine spiradenoma is a benign tumor which probably originats in the coil of the eccrine sweat gland. It usually presents as a solitary, slowly-growing, sometimes painful, reddish-brown, and intradermal or deeply subcutaneous nodule on the head and trunk. More than 97% of eccrine spiradenoma appear as solitary lesions. Occasionally, it may appear as multiple lesions, however they are rarely arranged in a linear or zosteriform distribution. A search of literature revealed only 17 internationally reported cases of linear or zosteriform eccrine spiradenomas, including 4 Korean cases. We herein present an unusual case of eccrine spiradenoma, showing multiple, large nodules with zosteriform distribution.

Clear cell hidradenoma, generally as an eccrine sweat gland origin, is a fairly uncommon tumor and occurs as a slowly growing, usually solitary nodule. The histological patterns vary from one tumor to another and in different parts of the same tumor. We experienced three cases of clear cell hidradenoma which were diagnosed by the histopathologic examination of the tumor mass removed by surgical excision. Clinical and histopathologic features of each case were reviewed and compared.

The result of compensatory sweating after surgical treatment for essential hyperhidrosis had problems in objectivity and validity because it mainly depended on the subjective symptoms of patients. Therefore, we tried to evaluate more precisely and objectively, the distribution and degree of compensatory sweating by D.I.T.I.(Digital Infrared Thermographic Imaging) with subjective symptoms.

Giant vascular eccrine spiradenoma is a rare benign tumor of the sweat gland, which differs from common eccrine spiradenoma in both its larger size and marked vascularity. It is emphasized that this rare type of spiradenoma is commonly misdiagnosed as an angiomatous lesion or a malignant tumor due to its hemorrhagic and ulcerative features. We report a rare case of giant vascular ecrine spiradenoma that was mistaken as a malignant tumor due to hemorrhaging and ulceration.

Introduction: Syringocystadenoma papilliferum (SCAP) is a relatively rare benign adnexal skin tumor which can manifest in a variety of clinical forms. Nearly one-third of cases are known to develop within a pre-existing nevus sebaceus (NS). The peculiar feature of this case was the appearance of a large exophytic tumor within a congenital verrucous plaque, which raised the suspicion of a malignant transformation. This is a case of a young Filipino adult with an unusual presentation of syringocystad- enoma papilliferum in a nevus sebaceus mimicking squamous cell carcinoma. Case report: A 27-year-old Filipino female presented a persistently enlarging exophytic pedunculated cribriform tumor within a congenital verrucous plaque on the left temporal area. The tumor started to appear when she was 20 years old. One month prior to consult, it rapidly increased in size and bled on gentle manipulation. She has neither comorbidities nor any family history of a similar condition. Her physical examination was normal, with no palpable lymphadenopathies. The biopsy showed syringo- cystadenoma papilliferum on a nevus sebaceus. She underwent carbon dioxide (CO2 ) laser excision under local anesthesia. The procedure was uneventful and the patient is on regular follow-up and close monitoring for any possible malignant change or recurrence. Conclusion A case of syringocystadenoma papilliferum on a nevus sebaceus mimicking squamous cell carcinoma in a Filipino female treated with carbon dioxide laser excision was presented. The unusual presentation of SCAP can mimic malignancy and histopathologic evaluation is warranted to rule out malignant transformation for proper management.
Tubular Sweat Gland Adenomas

Impaired sweating reportedly has been associated with a high incidence of heat pyrexia. An important cause is attributed to sweat gland fatigue following intense prolonged sweating. For further investigation, sweat gland fatigue was induced by heat exposure for 2 hours in a hot room (dry bulb 46c, wet bulb 37c) with 9 healthy subjects. Sweating rate of the right forearm increased progressively for the first 45 minutes with a maximum value of 40.0mg/4. 91 cm2/15 min followed by a slow decrease to 24.9 mg/4.91cm2/15 min at the end of 2 hours. Active sweat pores decreased in number following 2 hours of heat exposure but the differences were not significant statistically. In spite of the higher sweat rate on the back, the number of active sweat pores was smaller as compared to the right forearm. Na+ concentrations of the second hour sweat collections were higher than those of the first hour with difference of 14. 9 mEq/l on the right forearm and 12.3 mEq/1 on the back.
