ABSTRACT

PURPOSE: The laparoscopic adrenalectomy (LA) has become the preferred procedure for adrenal tumors due to many advantages; a more rapid and comfortable recovery, shortened hospitalization period, and fewer complications. This study reports on an initial 4 year period of experience with LA and describes various unusual findings encountered during the treatment. METHODS: From February 1997 to November 2000, a total of 20 LA were performed. Of the several LA techniques previously described we prefer the transabdominal approach in the lateral decubitus position utilizing 3 or 4 trocars, and this method was employed in all the cases presented here. RESULTS: All 20 patients had a unilateral tumor. The pathological findings consisted of 11 aldosteronomas, 6 Cushing adenomas, 2 pheochromocytomas and 1 cortical carcinoma. Of the 20 patients, 18 were successfully operated with the laparoscopic procedure and the remaining 2 cases were converted to open adrenalectomy. The reasons for conversion were sudden cardiac arrest of unknown origin in one and intraoperative bleeding due to periadrenal massive fat in the other. During LA, 2 patients with non-catecholaminesecreting cortical adenomas pathologies displayed abnormal EKG findings, which reverted to normal after the operation. The average complete LA operation times was 186 minutes in the first 9 cases and 132 minutes in the next 9 cases. The first oral intake was started within 24 hours in all cases. There were no postoperative complications, operative morbidity or mortality. The average hospital stay was 6.2 days in the first 9 cases and 4.2 days in the next 9 cases. CONCLUSION: LA is a relatively fast and safe method and has become is accepted as the preferred procedure for adrenal tumors but it requires good perioperative preparation. Surgeons and anesthesiologists need to be aware of the possible cardiovascular complications and of the problems inherent in the manipulation of the adrenal gland during LA.

ABSTRACT

Hepatosplenic gamma delta-cell lymphoma is a rare histologic type of peripheral T-cell lymphomas, clinically characterized by predominant involvement of liver and spleen, no or little adenopathy, and an often aggressive course. We report a case of bone marrow involvement of hepatosplenicgamma delta-cell lymphoma in a 21- year-old woman who presented with fever, anemia, thrombocytopenia, and hepatosplenomegaly. A lymphoma was found subsequently by bone marrow biopsy and computed tomography scan of the abdomen and pelvis. Immunologic characterization of lymphoma cells in bone marrow revealed positivity for CD2, CD3, and CD16/56, and negativity for CD4, CD5, CD7, CD8, CD34, and terminal deoxynucleotidyl transferase (TdT). Conventional cytogenetic studies revealed the presence of isochromosome 7q. Using the PCR-SSCP technique, monoclonal gene rearrangement of the T-cell receptor gamma chain was demonstrated. Thus, we could make a confirmatory diagnosis as hepatosplenic gamma delta-cell lymphoma.

ABSTRACT

BACKGROUND: Mantle cell lymphoma/leukemia (MCL) is a distinctive disease entity that has been characterized by specific histopathologic, immunologic, and cytogenetic features. The characteristic cytogenetic abnormality of MCL is t(11;14)(q13;q32), that results in cyclin D1 overexpression. We have experienced 12 MCL cases with bone marrow involvement that were lacking evidence of t(11;14). We tried to review the cases. METHODS: We reviewed the bone marrow findings, immunophenotypic, cytogenetic studies including fluorescent in situ hybridization (FISH) analysis using IGH/CCND1 probes and medical records of 12 patients that were diagnosed with MCL based on immunophenotypic results during the period 1997 to 2001. RESULTS: The patients had a median age of 63 (50-70) years with male-to-female ratio of 3:1. All patients showed hepatosplenomegaly with varying degrees of peripheral blood involvement (2-93%), and lymphocytosis was found in 7 cases. Other presenting features were palpable lymph nodes (83%) and B symptoms (25%). The malignant cells were quite heterogenous in morphology from centrocytic to blastic variants. Most cases showed typical immunophenotypes-expression of CD19, bright CD20, FMC7, CD5 and bright-light chains with negative CD23. Immunohistochemical staining with cyclin D1 on marrow biopsies showed mostly negative results. Among the eleven cases in which cytogenetic studies were possible, four cases showed complex karyotypes, and three that involved 14q32. Strikingly, no one showed t(11;14) in G-banding analysis and only 2 cases showed IGH/CCND1 rearrangement by FISH. CONCLUSTIONS: Most MCL cases with typical immunophenotypic findings did not show evidence of specific cytogenetic features. Although further workups for molecular pathogenesis and clinical follow-up of the above cases need to be done, we suggest a new disease entity, t(11;14)-negative MCL.

ABSTRACT

A 17-year-old-boy with a bilateral incomplete cervical rib, upon abduction of his left arm at 45 degrees, had immediately begun to show symptoms of severe tingling, claudication, pallor, and weakness of his left upper extremity. These symptoms were aggravated at 90 degrees, leaving him debilitated from his work in the printing office. Transfemoral positional subclavian arteriography revealed total occlusion of the subclavian artery immediately distal to a cervical rib during 90 degrees abduction. Resection of the anterior scalene and medial aspect of the middle scalene muscles, cervical and first ribs, and arteriolysis were performed via a combined supraclavicular and infraclavi cular approach. He has returned to work as a printer with marked relief of symptoms and has remained asymptomatic over follow-up periods of 10 months.
