Painless, gradually enlarging, subcutaneous lesion of the eyelid

Perivascular epithelioid cell tumors (PEComas) are a family of rare mesenchymal tumors with discrete histological and immunohistochemical characteristics. Even rarer among them are cutaneous and subcutaneous PEComas. We describe a 34-year-old woman who presented with a large anterior abdominal subcutaneous lesion showing intact overlying skin and no obvious invasion of the abdominal musculature. A wide local excision was performed. Histopathology revealed a solitary tumor measuring 75 × 55 × 90 mm with epithelioid cells in nests with thin fibrovascular septa and spindle cells. Resection margins were clear with no invasion to the skin or rectus sheath. Tumor cells were positive for HMB-45 but negative for other markers. This is the largest subcutaneous PEComa reported to date.

Subcutaneous Lesion

Venous varix on the volar aspect of the digits or the hand is a rare subcutaneous lesion that is usually described as a firm, blue, and painful single nodule that contains thrombus. However, there have been no reports about venous varix on the dorsal aspect of the digits or the hand, so its features are unknown. We treated two patients who each had a soft blue painless mass on the dorsal aspect of the thumb that became enlarged with the tourniquet test. Ultrasonography and/or magnetic resonance imaging were used for assisting with the preoperative diagnosis, and showed each lesion was composed of two or more varicosities. Each mass was removed and was diagnosed as a venous varix without thrombus by histological examination.

Subcutaneous Lesion

A review of our cases of granuloma annulare in the hand revealed that it presented as either an annular or subcutaneous lesion, most commonly on the dorsum of the metacarpophalangeal joint of the middle or ring fingers. Lesions were approximately 10 mm in diameter and the diagnosis was confirmed by surgical biopsy. The majority of cases resolved spontaneously within 1 year, and recurrence, though common, did not necessitate a further biopsy.

Subcutaneous Lesion

Background: Salivary duct carcinoma (SDC) is a rare aggressive tumor. Most tumors are not confined to the salivary ducts; rather, they invade the major and minor salivary glands. Only a few case reports on such tumors in other primary sites have appeared. Case presentation: A 40-year-old male complained of right hearing loss (a common condition), but we made an extremely rare diagnosis of an SDC in the external auditory canal (EAC). EAC cancers are frequently misdiagnosed. In our patient, the otoscope revealed a smooth, bulging subcutaneous lesion with a non-epithelial defect suggestive of a benign lesion. However, an SDC of the EAC was confirmed through pathological and immunohistochemical analysis. Conclusions: We suggest detailed evaluation of even smooth EAC subcutaneous lesions to avoid erroneous diagnoses. To the best of our knowledge, this is the first report of SDC in the EAC.
