[Calcium pyrophosphate dihydrate crystal deposition disease: a clinicopathologic analysis of 20 cases].

Objective: To investigate the clinicopathologic features of calcium pyrophosphate dihydrate crystal deposition disease (CPPD-CDD).

Methods: The clinical and pathologic profiles were retrospectively analysed in 20 cases of CPPD-CDD.

Results: CPPD-CDD was far more common in women, most frequently involving joints, especially the knees and presenting with various arthrisis.

Clinical and pathological characteristics of giant cell angioblastoma: a case report.

Unlabelled: Giant cell angioblastoma (GCAB) is an extremely rare soft tissue tumor of early childhood and only five cases have been described to date. As such the clinical, pathological, and prognostic features are poorly defined. We prensent here a new case of GCAB in bone of a child aged 4-years old.

[Clinicopathologic features of calcifying fibrous tumor with reappraisal of its histogenesis].

Objective: To study the clinicopathologic features and histogenesis of calcifying fibrous tumor (CFT).

Methods: The clinical manifestations, histopathologic characteristics and immunophenotype were analyzed in 11 cases of CFT.

Results: The male-to-female ratio was 5:6, with a mean age of 38 years and age range of 25 to 52 years.

[Clinicopathological features of multiple mucosal neuroma without multiple endocrine neoplasia type IIB].

Objective: To investigate the clinicopathological features of multiple mucosal neuromas without multiple endocrine neoplasia type IIB (non-MEN-IIB MMN).

Methods: Three cases of non-MEN-IIB MMNs were analyzed for the clinical manifestations and histopathological characteristics.

Results: All the 3 cases were females, age ranging from 30 to 45 years.

[Lipomatosis of nerve: a clinicopathologic analysis of 15 cases].

Objective: To study the clinicopathologic features of lipomatosis of nerve (NLS).

Methods: The clinical, radiologic and pathologic features were analyzed in 15 cases of NLS.

Results: There were a total of 10 males and 5 females.

[Clinicopathologic study of giant cell angioblastoma].

Objective: to study the clinicopathological features, imaging characteristics, immunophenotypes and differential diagnosis of giant cell angioblastoma (GCAB).

Methods: a case of GCAB in the left middle-upper tibia and fibula was studied by light microscopy, X-ray and CT imaging, immunohistochemistry.

Results: X-ray and CT imaging showed a clearer lesion in the left middle-upper tibia than in the ipsilateral fibula with enlarged ostealleosis and increased inhomogeneously medullary cavity density, irregular thickening of cortical bone, local cortical default at the inner edge, soft tissue swelling around the abnormal bone.
