Primary pulmonary malignant melanoma is rare (0.01% of pulmonary cancers); only 25 cases are published in the literature. The diagnosis of primary pulmonary malignant melanoma is controversial, the pathogenesis is unknown and a pulmonary metastasis from a mucocutaneous melanoma is the main differential diagnosis. The diagnosis is based on the strict application of the Jensen criteria published in 1967. ⋯ This observation raises the question of (18)FDG CT-PET in this situation, particularly of the whole body, by extrapolation from the recommendations in mucocutaneous melanoma. The lack of increased uptake on (18)FDG CT-PET could be a new paraclinical diagnostic criterion to add to the clinical criteria of Jensen. This report is the first, which shows the results of (18)FDG CT-PET (standard and whole-body) under this situation.

Case Reports
[Isolated abscess of the thoracic and abdominal wall: an exceptional form of tuberculosis].
Isolated thoracic parietal involvement is a very rare form of tuberculosis and multifocal localization is exceptional. It often poses a diagnostic problem with parietal tumours requiring recourse to surgical biopsy. We report a case of tuberculous abscess localized to the anterior and superior part of the chest wall with a second abdominal localization but without any pulmonary involvement. ⋯ The diagnosis was confirmed by histological examination of a surgical biopsy and bacteriological examination of a percutaneous aspirate of the collection. Standard anti-tuberculosis treatment was given for nine months with good clinical and radiological resolution. In this case report, we study the anatomical and clinical features of this condition and discuss the diagnostic difficulties.
