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.

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.

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.

Pulmonary hyalinizing granuloma (PHG) is a rare disease that usually presents with multiple bilateral pulmonary nodules and characteristic histological findings, with hyalinized collagen lamellae. Because of the absence of characteristic radiologic and clinical features, PHG is usually diagnosed after surgical resection or biopsy. We performed thoracoscopic wedge resection for a pulmonary nodule located in the right lower lobe that proved to be PHG histopathologically. We report two cases along with a review of the literature.
