A primary hepatic lymphoma in a patient with Crohn's disease receiving thiopurine and anti-TNF therapy: a case report.

Primary hepatic lymphoma is a rare variant of non-Hodgkin's lymphoma with an incidence of 0.016% of all non-Hodgkin lymphomas. The most common histologic subtype is large diffuse B-cell lymphoma.

[Eosinophilic cystitis: review of nine cases].

Background: Eosinophilic cystitis is a rare inflammatory pathology. It remains a poorly understood entity.

Aim: To report a series of adult cases of eosinophilic cystitis mimicking a bladder tumor.

[Adult's cryptorchidism: clinical and therapeutic aspects. About 100 cases].

Background: Cryptorchidism is a pathological condition defined as the failure of the testis descending into the scrotum. It is a rare condition in adults.

Aim: To study clinical and therapeutic aspects of cryptorchidism in adults.

[Mixed germ cell tumor of the ovary with rhabdomyosarcomatous component. A case report].

Malignant germ cell tumors of the ovary are rare representing 3% of all ovarian neoplasms. Hence, they are the most common ovarian malignancy in girls and young women and account for approximately two-thirds of the ovarian cancers that occur in the first two decades of life. Germ cell tumors constitute a heterogeneous group of tumors and are often mixed associating at least two different tumoral components.

[Isolated primary gastric localization of a mantle cell lymphoma].

Primary mantle cell lymphoma of the digestive tract is uncommon; it rarely involves the stomach and generally manifests as a lymphomatous polyposis. Isolated gastric localization is exceedingly rare. We present a case of a 57-year-old man who presented with a six-month history of atypical epigastric pain.

Multiple myeloma and cutaneous anaplastic large T-cell lymphoma in the same patient: is there a causal relation?

Synchronous occurrence of lymphomatous proliferations of B and T lineage in the same patient is a very rare event and still poorly understood. All the cases reported in the English language literature are described as single case reports. We report a case of 49-year-old man, with 2-year history of multiple myeloma, presented with a raised, erythematous and ulcerated nodule in the anterior aspect of his right thigh.

Solitary fibrous tumour of the central nervous system: pathological study of eight cases and review of the literature.

Aims: Solitary fibrous tumours (SFT) of the central nervous system are rare neoplasms that usually present as dura-based masses and clinically resemble meningiomas. Histologically, they can be similar to haemangiopericytoma or fibrous meningioma. We present herewith a pathological study of eight patients with SFT and compare our results with the published data.

Malignant eccrine spiradenoma: a new case report.

Malignant eccrine spiradenoma is an extremely rare skin tumor of sweat gland origin. In most cases, it arises in pre-existing benign eccrine spiradenoma. We report an additional case of malignant eccrine spiradenoma.
