[Morphologic and histopathologic analysis of testicular appendages].

Objective: To investigate the incidence of testicular appendages, observe their morphology, and analyze their histopathological origins.

Methods: We observed 67 testes in 54 patients (15 children and 39 adults) undergoing scrotal surgery, investigated the incidence of testicular appendages, and identified their histopathological origins. We used the Chi-square test to compare the findings from the children and adult patients, with P < 0.

[Ectopic mesonephric duct cyst with ectopic testicular malignancy: a case report and literature review].

Objective: To report a rare case of ectopic mesonephric duct cyst with ectopic testicular malignancy and improve the diagnosis and treatment of the disease.

Methods: We retrospectively analyzed the clinical data of a case of ectopic mesonephric duct cyst with ectopic testicular malignancy, reviewed relevant literature at home and abroad, and investigated the pathogenesis, diagnosis and treatment of the disease.

Results: A large cyst and the right ectopic malignant testis were removed via abdominal incision, and the left undescended testis was lowered into the scrotum.

[Gastrointestinal B-cell lymphoma: a morphologic and immunohistochemical study of 194 cases].

Objective: To study the morphologic and immunohistochemical features of gastrointestinal B-cell lymphomas.

Methods: One hundred and ninety-four cases of gastrointestinal B-cell lymphoma were retrieved from the archival file. The clinical features and pathologic findings were reviewed.

[Ultrastructural changes of hepatocyte fibrogenesis in cholelithiasis].

Objective: To explore the ultrastructural changes of hepatocyte fibrogenesis in cholelithiasis in biliary tract.

Methods: l0 liver biopsies were taken from the patients suffered from gallstone and choledocholithiasis during surgical treatment and the ultrastructural changes were observed under electromicroscope.

Results: There were plentiful collagenous microfibrils (CMFs) grown within some hepatocytes.
