[Lymphomatoid granulomatosis]

Lymphomatoid granulomatosis (LG) is characterized as an angiodestructive cell proliferation. It occurs commonly in the lung, but skin manifestations are present in 45% of the patients and the involvement of the central nervous system is not rare, too. The progression into malignant lymphomas is 13-53%. The authors review the history of two patients with LG. The involvement of the lung with LG was in the first case. The histological investigation of the lung after pulmonectomy has given the diagnosis. Coombs positive hemolysis and antinuclear factor positivity were found in this patient, too. She has not been transformed into lymphoma in 3 years. In the second case LG was diagnosed after large bowel resection. After a half year follow-up the liquor investigation showed the central nervous system manifestation of lymphoma.

[Peripheral nerve injuries as a rare complication of cervical lymph node excision for diagnostic purposes]

During the last 3 years 263 patients were admitted who underwent diagnostic lymph node biopsy. Complications were observed only in 4 cases. In these cases, following cervical lymph node excision from the supraclavicular region, sectioning the spinal accessory nerve and branches of brachial plexus resulted in the "shoulder syndrome" which is characterized by a weakened, deformed, and often painful shoulder. Attention is called to the possibility of nerve injury during diagnostic excision of cervical lymph nodes. Most often the spinal accessory nerve and branches of brachial plexus are transected with subsequent deformity and decreased range of motion of the shoulder, which could influence deeply the quality of patient's life.
