Calcifying fibrous pseudotumors (CFP) are rare soft tissue tumors that have unique histopathologic features characterized by a dense hyalinized collagenous tissue interspersed with benign spindle cells, lymphoplasmacytic infiltrate, and psammomatous or dystrophic calcifications. We report here on a case of calcifying fibrous pseudotumors in the pleura and provide a literature review.

Fibroma of the tendon sheath is a slow-growing tumor, adherent to mainly the volar aspect of the tendon sheath of the finger or hand. Histopathologically, these tumors are always well-circumscribed and may be lobulated. They are largely composed of interlacing bundles of hyalinized, hypocellular fibrous tissue with the occasional increased cellular area. A characteristic feature is the presence of slit-like vascular channels. They are benign lesions with a tendency to recur in upto 25% of cases, although becoming more generally recognized are not yet familiar to dermatologists. Herein, we report two cases of fibroma of the tendon sheath.

Sclerotic fibroma is one of the histologic variants of soft fibroma. Clinically, it presents as a solitary skin-colored nodule, usually less than 1 cm in diameter in adults and has a wide anatomical distribution. Histologically, it is a well-circumscribed dermal nodule composed of hypocellular hyalinized collagen bundles separated by clefts and arranged in a storiform pattern. Treatment with simple excision is curative. We report a case of sclerotic fibroma in a 34-year-old man who presented an asymptomatic, bean-sized, intracutaneous nodule on his back for 3 years.

Microcystic stromal tumor (MCST) of the ovary is a rare subtype of ovarian tumor first described in 2009. Although high nuclear expression of β-catenin and β-catenin gene (CTNNB1) mutation are related with ovarian MCST, the origin and genetic background of ovarian MCST remain unclear. In this study, two cases of ovarian MCST are presented. Microscopically, the tumors showed a microcystic pattern and regions with lobulated cellular masses with intervening hyalinized, fibrous stroma. Tumor cells of both cases were stained with CD10, vimentin, and Wilms tumor 1. Genetic analysis was performed and β-catenin gene (CTNNB1) mutation in exon 3 was detected in both cases. This is the first report in regards of detecting CTNNB1 mutation in ovarian MCST through the use of pyrosequencing (a novel sequencing technique).
