Periocular Trichoblastoma: A Diagnostic Dilemma.

A 41-year-old woman presented with a large medial canthal lesion that extended over the midline. Excisional biopsy revealed a multinodular basaloid tumor, located within the dermis and subcutaneous fat that extended into skeletal muscle at the deep and peripheral margin. Histology was consistent with trichoblastoma. A review of the literature reveals a lack of specific and sensitive immunohistochemistry markers to establish the diagnosis of trichoblastoma. Following reconstruction, the patient has shown no signs of recurrence of the lesion at 24 months.

Lungs and subcutaneous metastases from a solitary fibrous tumour of the pancreas.

Solitary fibrous tumour is an uncommon mesenchymal neoplasm previously thought to only originate from the pleura; it is seen only rarely in an extra-pleural location. We report the first case of pancreatic solitary fibrous tumour in an 87-year-old woman that has metastasized to the lungs and subcutaneous tissue. We have identified a solitary mass excised from the groin region, which is positive for CD34 and vimentic marker with high proliferative rate, nuclear atypia and cellular necrosis. Imaging studies confirmed a slow-growing solitary mass in the uncinate lobe of the pancreas with evidence of lung metastasis.
