Authors report on a 75-year-old man with bilateral testicular lymphoma. He complained of painless right testicular enlargement. Orchidectomy was indicated by ultrasound examination and the diagnosis (large cell, non-Hodgkin lymphoma B-cell origin) was established by histology and immunohistochemistry. Two months later, the left testis enlarged, orchidectomy was performed, and a lymphoma with identical histology was found. PET revealed retroperitoneal spread of the tumor. Irradiation (18 Gy) was applied. Three months later, because of gastric metastases of the lymphoma the patient underwent CVP and CAVP (Cyclophosphamide, Adriablastin, Vincristin, Prednisolone) chemotherapy. Despite of the repeated courses, eleven months after the primary diagnosis the patient died due to of multiple metastases.

Anti-apoptotic proteins Bcl-2 and Bcl-xL are overexpressed in 80% of non Hodgkin's lymphoma cells and are thought to play an important role in the resistance of lymphoma cells to current chemotherapeutic agents. Gossypol, an orally-active polyphenolic aldehyde derived from the cotton plant, has been known to have potential anti-neoplastic activity. Recently, gossypol was found to bind to the BH3 binding groove of Bcl-xL and with lesser affinity to Bcl-2. The present study was conducted to determine whether gossypol increases the sensitivity of non-Hodgkin's lymphoma cells to the actions of chemotherapeutic agents by potentiating treatment-induced apoptosis. The interactions observed between gossypol and chemotherapeutic drugs were analyzed using the median effect principle (CalcuSyn analysis). Our data showed that treatment of Ramos cells with gossypol not only induced cell arrest on the G(0)/G(1) phase, but also augmented apoptosis and growth inhibition induced by etoposide (VP-16), doxorubicin hydrochloride (ADM), vincristine (VCR), and paclitaxel (taxol). However, when gossypol was combined with cisplatin (DDP) an antagonistic effect was observed. Gossypol-induced cell cycle arrest was accompanied by decreased expression of cyclin D1 in Ramos cells. In addition, the peroxisome proliferator-activated receptor (PARP) pathway is, at least in part, involved in the gossypol-induced apoptosis when combined with VP-16. These data indicate that single-agent gossypol is effective in inhibiting growth of non-Hodgkin's lymphoma cells in vitro and combination studies with certain secondary chemotherapeutic agents further demonstrate it's synergistic cytotoxicity. These findings support future preclinical and clinical studies of gossypol in the treatment of non-Hodgkin's lymphoma.

Primary thyroid lymphoma is a rare clinical entity, which does not exceed 5% of the diagnosed lymphomas, occur more frequently in women than in men, with a peak incidence in the sixth decade of life. The relationship with chronic thyroiditis is well known. The Hodgkin subtype even rarer; little described in the literature; Posing a diagnostic problem. Diagnostic confirmation is usually carried out on the surgical specimen. To better understand this entity, we report the case of a 64-year-old patient, with no notion of chronic thyroiditis, admitted for Hodgkin's lymphoma of the thyroid, diagnosed on an anterior cervical mass. Thyroidectomy with histopathological and immunohistochemical studies confirmed the diagnosis. The patient had received chemotherapy type ABVD (Adriblastin-Bleomycin-Vinblastine-Dacarbazine) and programmed for radiotherapy.
