Key Clinical MessageWe report a case of hemosiderotic dermatofibroma presenting as a brown‐black‐colored nodule with peripheral extensions, which mimics melanoma. Histopathology showed completely benign features with no atypia or mitosis. Nodular extensions of childhood dermatofibromas may be related to the growth of the child not necessarily pointing to a malignant process.

Tuberculosis is an important health problem in developing countries, with varying clinical presentations depending on the organs/systems involved. Tuberculosis is mostly seen in immuno-compromised individuals, such as those with acquired immune deficiency syndrome or malignancies. Here we report a case of a spleen tuberculoma in a 29-year-old male patient with no known immune deficiency. He first presented with abdominal pain, and subsequent ultrosonographic examination revealed a splenic lesion of 10 cm in diameter. A computerized tomography scan of the abdomen confirmed the presence of a solitary, hypodense, septated cystic lesion. Lack of evidence supporting the presence of a splenic infection or a primary/metastatic malignancy prompted explorative surgery where a septated abscess formation was discovered and splenectomy was performed. Histopathological examination revealed granulomatous inflammatory changes with Langerhans-type giant cells, which are consistent with tuberculosis. For a period of two months, antituberculosis therapy with four drugs, isoniazid, rifampicin, pyrazinamide, and ethambutol, was carried out. Pyrazinamide and ethambutol were quitted at the end of two months. Theraphy with isoniazid and rifampicin was planned for an additional 10 months. We would like to call attention to yet another atypical presentation of extrapulmonary tuberculosis. spleen tuberculosis; abdominal tuberculosis; splenic abscess

Two primary tumors are not seen so often together in the stomach. Adenocarcinoma and associated tumors including gastric lymphoma (especially MALT lymphoma), carcinoid, leiomyosarcoma and rhabdomyosarcoma constitute most of the reported series. Rarely adenocarcinoma and associated GIST cases were reported. It is important to report concurrent gastric lymphoma and GIST case since it is extremely rare in the English literature.

We believe YKL-40 may play a significant role in pterygium pathogenesis.

The results suggest that endocan may have a role in the pathogenesis of pterygium.
