The clinical data of one patient with left ear temporal eccrine spiradenoma in our hospital were retrospectively analyzed. Eccrine adenoma, also known as the eccrine spiradenoma (eccrine spiradenoma, ES), a benign tumor derived from sweat glands, are typically single spherical or oval slow increases substantive or cystic nodules block, diameter of 1-2 cm, skin color or light blue. It's a rare case for young women, shorter onset time, more huge tumor, skin ulceration and exudate. This disease is a benign tumor, surgical resection could lead to a good result. It should be followed up after surgery.

A 2-year-old girl had variably-sized, relatively well demarcated, depressed brownish patches on the left shoulder, back, and both legs from the age of 1 month. The biopsy specimen from the left shoulder showed an increase in the number of normal intradermal eccrine ducts and coils, which was compatible with pure eccrine nevus. The clinical manifestation of our case, including brownish depressed patches, was unique compared to other reported cases.

Clear cell hidradenoma is an uncommon benign skin appendageal tumor that typically involves the dermal layer of the head, face, and extremities. The breast is a rare site for this lesion, with only two documented cases, which were determined based on mammogram and sonogram findings. We present a case of clear cell hidradenoma of the axillary tail with radiological findings and a literature review.

Eccrine spiradenomas are rare, benign, cutaneous tumors that originate in the sweat glands. Eccrine spiradenomas in the breast are very rare and only a few cases have been reported. We report here on the case of a 47-year-old woman with superficial masses in the breast and these masses had gradually increased in size during follow-up. They were confirmed to be an eccrine spiradenoma on pathologic examination. There have been a few reports about the radiologic findings of eccrine spiradenomas of the breast. This is the first case of an eccrine spiradenoma in the breast that was characterized by multiple imaging modalities, including mammography, ultrasonography and MRI. The lesion in our patient was first diagnosed as an epidermal inclusion cyst based on the imaging findings and the mass's superficial location. Although the mammographic and ultrasonographic imaging findings of eccrine spiradenomas and epidermal inclusion cysts are similar, the MRI findings are different between epidermal inclusion cysts and eccrine spiradenomas. Eccrine spiradenomas should be considered in the differential diagnosis of cutaneous and subcutaneous lesions of the breast.

A 79-year-old male presented with left ocular pain. Evisceration and silicone ball implantation were performed after a diagnosis of phthisis. He returned six weeks later because of left facial erythematous swelling, tenderness, mild fever, chills and cough. His condition was diagnosed as orbital cellulitis. Despite two weeks of empirical antibiotic therapy, the symptoms worsened. A subsequent orbital computed tomography scan revealed enhanced soft tissue infiltrations in his left orbit and eyelid. Biopsy showed a diffusely infiltrating tumor of signet ring cell cytology. A systemic evaluation revealed multiple bone metastases. Based on this evidence, the patient was diagnosed with a very rare case of histiocytoid variant eccrine sweat gland carcinoma with multiple bone metastases.

Syringocystadenocarcinoma papilliferum (SCACP) is a rare form of adenocarcinoma of the skin. This is the malignant counterpart of syringocystadenoma papilliferum (SCAP) and usually develops on the scalp in a long-standing lesion identified clinically as SCAP. We describe a 65-yr-old Korean man with a nodule on the right supra-pubic area with a 2-yr duration. Histologically this tumor had a similar overall configuration as in SCAP, but the tumor was asymmetric and poorly circumscribed, extending into the deep dermis and showed cytologic atypia. The tumor cells showed positive reaction to GCDFP-15, but negative reaction to CEA and HMFG-1. We established the diagnosis of SCACP in the patient, and a wide excision was performed to remove the tumor. The patient has been well without relapse or metastasis for 2 yr.
