Pilomatricoma, also known as calcifying epithelioma of Malherbe, is an asymptomatic, slow-growing, benign dermal neoplasm that originates from hair cortex cells. The most common sites are the head and neck (68.2%), followed by the trunk (14.4%) and the upper (15.3%) and lower (2%) extremities. The majority (60%-70%) of tumors develop in the first 2 decades of life. A typical pilomatricoma presents as a firm, calcified, dermal nodule appearing as a solid mass in subcutaneous tissue on computed tomography or magnetic resonance imaging.This article describes the case of a 42-year-old man who presented with nontender soft tissue swelling in the right ankle joint. Radiographs and magnetic resonance imaging findings showed an inflamed cystic mass with calcification in the lateral malleolar area of the right ankle joint. These atypical magnetic resonance imaging features around the ankle joint led to confusion with other disease entities, including chronic bursitis, pigmented villonodular synovitis, rheumatoid nodules, and gout. After complete excision of the mass, histological examination revealed a cystic pilomatricoma.Although rare, a cystic pilomatricoma should be considered in the differential diagnosis of soft tissue masses with calcification.

Ten of 12 red-bellied short-necked turtles from a single clutch presented at 9 months of age with multiple white to tan nodules on their feet. Histologically, the nodules were composed of large periarticular deposits of mineralized crystalline material that extended into the joint spaces of interphalangeal joints and was surrounded by granulomatous inflammation and fibrosis. Crystallographic analysis determined the material to be apatite (calcium phosphate hydroxide) consistent with the tumoral calcinosis form of hydroxyapatite deposition disease (HADD). HADD has previously been described in aquatic turtles and rarely lizards and must be differentiated from gout in reptiles. A cause for the tumoral calcinosis lesions in these turtles could not be determined; however, based on previous reports in this species, a species-specific predilection, in conjunction with unknown environmental factors, is suspected. The use of the terms HADD, pseudogout (calcium pyrophosphate crystal deposition disease), and calcinosis circumscripta has been inconsistent, creating confusion in the literature.

Urate is a frequently measured blood test in people with gout and those at risk of gout. Although gout is potentially curable with long-term urate lowering therapy, confusion about the details of urate measurement has contributed to suboptimal care. In this article, we provide recommendations regarding urate testing in gout, focusing on the use of this test in clinical practice.

A 92-year old woman was admitted to the geriatric department because of a confusional state due to a urinary tract infection, a severe dermatitis and gout. An incomplete tetraplegia was found on physical examination. Radiological examination showed a large gouty tophus causing spinal cord compression and destruction of the dens. Gouty involvement of the spine is a less common complication of the disease. Optimal treatment of gout is important to prevent the development of such severe complications.

Sialosis is observed in relation to diabetes, alcoholism, and malnutrition. An assumed relation between gout and sialosis is probably based on confusion that originated from the therapeutic use of phenylbutazone for gout and the sialadenitis that the medication caused. This report describes a case of sialosis in a patient with a longstanding history of gout that was idiopathic in origin.
