- Authors experienced a rare adenocarcinoma arising in presacral sacrococcygeal teratoma in a adult and herein reported. The patient was a 52 year old female admitted because of lower abdominal pain for 5 to 6 months. Past and familial history were unremarkable. On rectal examination a mass was palpated 3 cm above the anal verge. The large bowel was displaced by an extrinsic mass but there was no evidence of intrinsic tumor lesion on barium enema, CT was done and showed a large presacral tumor attached to the sacrum.
Clinical impression was sacrococcygeal teratoma. Resected tumor mass was a relatively well circumscribed cystic mass, measuring 11 x 11 cm and the cystic content was previously evacuated. Inner surface showed ragged appearance, and focal nodular solid area was noted. On microscopic examination, the tumor revealed the derivatives of three germ layers and main components were tissues of respiratory tract. Sections from the solid area showed a well differentiated adenocarcinoma and with stromal, capsular and perineural invasion. Borderline malignant epithelial lesions are also noted suggesting the pathogenesis and progression of this tumor. There was no recurrence for one year after surgery in the follow up.

- Herein reported were three cases of papillary eccrine adenoma also called as tubular apocrine adenoma, characterized by dilated ducts containing eosinophilic secretion or kerain and intraluminal papillations. Case 1. A 23 year old male had a well defined erythematous nodule, measuring 1x1 cm. On the ankle of right leg over ten years.
Clinical impression was dermatofibroma. Microscopic features were those of papillary ecrine adenoma. Case 2. A 53 year old female had a well demarcated dermal nodule, measuring 1.5x1 cm. On the buttock. Cut surface exhibited relatively well circumscribed tumor with yellowish brown color, Microscopic features were those of papillary eccrine adenoma with alcian blue positive materials in their lumens. Case 3.
A 22 year old female had a showly growing hard painless small bean sized nodule at the metatarsal head area of right sole, measuring 2.3x1.8x0.7 cm. Clinical impression was calcinosis cutis. Microscopic features were those of papillary eccrine adenoma with foreign body granuloma and dystrophic calcification.
