Mechanomyoscopy as an objective method for determining the degree of decurarisation is particularly useful in the case of uncooperative patients and those who are incapable of adequate neck flexion mostly for spinal column diseases. The authors use for that purpose a Czechoslovak-made neuromuscular stimulator (LSN 110), with constant 50 Hz frequency of stimulation, 0.3 ms impulse duration, max. 50 mA and, depending on skin impedance, 5-140 V. The stimulator switch is manually controlled. The absence of muscular fatigue (fade) on single as well repeated stimulation lasting only a fraction of a second necessary to elicit muscular response does not rule out residual curarisation despite the fact that less than 70% of the cholinergic receptors are blocked. The only reliable sign of clinically sufficient decurarisation is the ability of the muscles of the hand to maintain contraction on tetanic stimulation of the motor point of the ulnar nerve in the wrist for at least 5 seconds without fatigue, and that even on a repeated exercise. This corresponds to a block of less than 60% of the cholinergic receptors. The patient's ability to raise his or her head and to keep it raised at 4 fingerbreaths for a period of 4 seconds is also a manifestation of clinically sufficient decurarisation. The value of forced expiratory volume is not conclusive evidence of sufficient decurarisation, it only gives a rough idea of its degree. The final decision is up to the an anaesthesiologist, his knowledge and experience based on objective data.

Recently, T-cell lymphoma localized to the subcutaneous tissue has been reported. We report the clinical, histologic, immunohistochemical, and molecular genetic findings in 6 patients who we believe had this peculiar T-cell lymphoma with its unique morphologic and clinical features. All patients presented with deep-seated nodules, most frequently on the extremities, and with systemic complaints of low-grade fever, fatigue, myalgias, and weight loss. In all cases, the neoplastic lymphocytic infiltrate was confined to the subcutaneous tissue, predominantly in a lobular pattern. Hemorrhage, necrosis, and rare erythrophagocytosis were also seen. Immunohistochemical staining was predominantly T-cell reactive (CD43, CD3, and CD45RO). Clonal rearrangements of the beta and gamma chains of the T-cell antigen receptor genes were found in 1 case. Three of the 6 patients died within 22 months of the diagnosis of lymphoma. We believe that subcutaneous T-cell lymphomas are a distinctive group of peripheral T-cell lymphomas with unusual clinical and morphologic features and that they should be distinguished from other types of lymphoma.

Primary adrenal lymphomas are rare. Most reported cases are of B-cell phenotype and follow an aggressive clinical course. We report a case of primary anaplastic large cell, CD30+ adrenal lymphoma developing in a 62-year-old woman. The patient presented with fatigue and vague right upper quadrant pressure. Computed tomography revealed bilateral adrenal masses. A right adrenalectomy was performed. Histologic evaluation showed islands of large atypical cells surrounded by eosinophilic acellular material. The tumor cells stained positive for CD45, CD45RO, CD43, and CD30. Epstein-Barr virus genome was identified in tumor cells using in situ hybridization. The patient was treated with chemotherapy and a 23-month follow-up examination showed no change in the size of the opposite adrenal gland and no other evidence of lymphoma.

Lymphomas secondarily involving the breast are uncommon, although they do represent the largest group of tumors metastatic to breast. A 20-year-old female with lymphoblastic lymphoma (LBL) presented here with 3 month history of weight loss, night sweats, fatigue and a mass in her left breast. Her physical examination revealed a left breast mass, lympadenopathy, bilateral pleural effusion and hepatomegaly. WBC count was 17,710/mm3 and LDH was mildly elevated. Breast ultrasound showed a 1.7 cm mass in the inner lower quadrant of left breast. Biopsy of the breast mass showed diffuse infiltration with small, round atypical cells which did not stain with CD20, CD43, CD34, cytokeratine and were positive for CD3. She was diagnosed as leukemic phase of a precursor T-cell LBL and treated with 6 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone), intrathecal methotrexate and cranial radiotherapy, achieving a complete response. She then was started on maintenance therapy. Four months later she returned with CNS involvement and was started on induction treatment. She had a very aggressive course of disease and died only 12 months after diagnosis. Breast involvement is very rarely seen in precursor T-cell LBL/ALL and in this patient occurred secondarily as part of widespread disease.

A 70-year-old Japanese man presented to our hospital with a 1-month history of progressive general fatigue and anorexia. A physical examination revealed severe anemic condition, mild persistent splenomegaly, and no palpable surface lymph nodes. He had pleural effusion and ascites, though no malignant cells were detected in the effusion. He eventually died without any diagnosis of his disease. Immunohistochemical staining of his tumor after autopsy showed atypical cells that were negative for epithelial membrane antigen (EMA), keratin (AE1/3), keratin-20, vimentin, factor VIII, leukocyte common antigen (LCA/T200; CD45), myeloperoxidase (MPO), terminal deoxynucleotidyl transferase (TdT), lysozyme, CD1a, CD3, CD4, CD10, CD15, CD20 (L26), CD21, CD23, CD34, CD43, CD56, CD68, CD79a, CD138, and EBER-1 in situ. Only a few scattered cells expressed CD30, but they showed no staining for anaplastic large-cell lymphoma kinase (ALK). A few scattered cells expressed S-100 antigen and the majority of cells dominantly expressed dendritic cell-associated antigens (CD35, FDC, Ki-M1p). In conclusion, we found this unknown primary tumor to be consistent with a follicular dendritic cell tumor with anaplastic features.
