An analysis of 294 enlarged peripheral lymph node biopsies in Ife, Nigeria, revealed that the underlying disease in 51.7% was chronic inflammation while malignant diseases accounted for 48.3%. The order of frequency of the lesions was reactive hyperplasia (29.3%), metastatic cancer (24.5%), malignant lymphoma (23.8%), tuberculosis (15.6%) and toxoplasmosis (3.7%). One-third of the metastases were of undetermined origin. The neck which accounted for 53% of the biopsies, was the most frequent site for tuberculous adenitis, toxoplasmic lymphadenitis, and malignancies. The axilla was involved in 15% of the cases and was the most common site for metastatic breast carcinoma. The inguinal lymph nodes were also involved in 24% of the cases and had the highest occurrence of melanoma, reactive hyperplasia and parasitic granuloma. The habit of bare-foot walking leading to repeated trauma and infection is implicated in the high incidence of inguinal node reactive hyperplasia. This study demonstrates that lymph node malignancies and chronic granulomatous infections present a problem of increasing diagnostic and therapeutic importance and furthermore, it emphasizes that physicians in Nigeria should consider toxoplasmosis in the differential diagnosis of peripheral lymphadenopathy.

The computed tomographic (CT) appearance, angiographic appearance, and clinical features of a patient with cervical Castleman disease, an uncommon disease of benign lymph node hyperplasia, are reported. CT scans showed a densely enhancing cervical mass. On external carotid angiography, the mass was seen as hypervascular with a capillary blush. Differential diagnosis included carotid body chemodectoma, vagal neuroma, tumor of the salivary gland, tuberculous adenitis and other granulomatous diseases, inflammatory lymph nodes, metastatic disease, and lymphoma.

Ionizing radiations have been shown to be carcinogenic to man as well as experimental animals. Malignancies following therapeutic radiation occur rarely. Over the past 10 years the authors recorded 10 cases of tumours in irradiated tissues. 3 occurred in patients irradiated for nasopharyngeal carcinoma, 3 were irradiated for tuberculosis adenitis, 2 for carcinoma of the cervix, 1 for carcinoma of the breast and 1 for basal cell carcinoma. The latent period for tumour induction following the irradiation varied from 5 years to 31 years. All these cases showed no evidence of recurrence or metastases of the original primary lesion; and the histology of the second primary differed from the first. Evidence of radiation damage was seen in all cases except for 2 patients who were treated for tuberculosis adenitis. The doses received varied from 900r to about, 9000r. Among the tumours produced, there were 3 cases of squamous cell carcinoma of the oral & postcricoid region, 2 cases of papillary carcinoma of the thyroid, 2 cases of adenocarcinoma of the rectum, 1 case of adenocarcinoma of the ethmoid, 1 case of osteosarcoma of the mandible and 1 case of extraskeletal osteosarcoma. The clinical features of these cases are discussed and other cases reported in the literature are reviewed.

The case of a 49-year-old transgender individual with a history of bilateral silicone breast implants and a right lung mass proven by biopsy to be a non-small cell lung cancer is presented. In addition to the primary malignancy, a positron emission tomography/computed tomography scan showed contralateral hypermetabolic adenopathy in the left axilla that was suggestive of nodal metastatic disease. Additional imaging and histological examination of the lymph nodes indicated silicone breast implant leakage and silicone adenitis as the underlying cause of the hypermetabolic axillary lymph node.
