One hundred consecutive patients with chest wall tumors undergoing resection during the past 8 years were reviewed. There were 55 female and 45 male patients with ages ranging from 12 to 84 years (median 54.5 years). Fifty patients had primary malignant neoplasms, 32 had metastases, and 18 had benign tumors. The tumor was located in the ribs in 78 patients and in the sternum in 22. The number of ribs resected ranged from one to eight (median 3.4). Sternectomy was performed in 22 patients. Overlying soft tissue was resected en bloc in 47 patients. Reconstruction was with prosthetic material in 57 patients and autogenous ribs in 11. There were 100 muscle transpositions, including 45 pectoralis major, 33 latissimus dorsi, and 9 serratus anterior. Hospitalization ranged from 4 to 80 days (median 9.6 days). Complications occurred in nine patients. One patient required tracheostomy. There was one operative death. Median follow-up was 31.5 months. Recurrent tumor developed in seven patients. All patients with benign tumor and 95% of patients with primary tumor not previously treated were alive. However, only 41% of patients with metastatic tumor were alive. Metastases were responsible for 89% of late deaths. We conclude that aggressive resection for chest wall tumor with reliable reconstruction can be accomplished safely and that early wide resection is potentially curative treatment.

This series presents six cases of a rare variant of dermatofibroma, characterized by marked clear cell change. All lesions occurred on the lower extremities of middle-aged adults (four women, two men), mostly with the clinical diagnosis of fibrohistiocytic lesion. Histological examination revealed well circumscribed, faintly stained dermal to subcutaneous lesions which were due to the overwhelming presence of clear cells (> 90%), some with prominent PAS-positive cytoplasmic granulation. Overlying epidermal hyperplasia as well as storiform arrangement of spindle cells, sclerotic collagen and some interspersed lympho-histiocytic infiltrate at the periphery of the lesion indicated the fibrohistiocytic origin. Individual histopathological peculiarities included: bizarre giant cells in two cases, perifollicular arrangement and haemangiopericytoma-like features with iron deposition in one case each. Immunohistochemically three of four lesions showed moderate reactivity for factor XIIIa and two of four with an anti-metallothionen marker E9, but were otherwise negative with a broad panel of markers. Electronmicroscopy in two cases revealed large pools of glycogen beside focal, prominent endoplasmic reticulum and lysosomes in some granular cells, but only optically translucent cells in cases of clear cells. Recognition of clear cell dermatofibroma is important as the differential diagnosis includes some entities with more serious outcome/considerations such as metastases of renal cell carcinoma, xanthogranulomatous reactions, balloon cell naevus/melanoma and clear cell sarcoma.
