BARCHAN: Blob Alignment for Robust CHromatographic ANalysis.

Two-dimensional gas chromatography (GC×GC) plays a central role into the elucidation of complex samples. The automation of the identification of peak areas is of prime interest to obtain a fast and repeatable analysis of chromatograms. To determine the concentration of compounds or pseudo-compounds, templates of blobs are defined and superimposed on a reference chromatogram.

[Pseudotumoral villonodular synovitis : a case report].

Background: Pseudotumoral pigmented villonodular synovitis is rare and diagnosis is difficult.

Aim: Report of new case.

Case: We report an original observation of a pseudotumoral pigmented villonodular synovitis occurred in a 28 years old patient with no recurrence after surgical treatment.

[Lateral nail squamous cell carcinoma: case report].

Background: Squamous cell carcinoma (SCC) of the lateral nail fold is rare, it has been suggested that trauma, roentgen radiation, arsenic exposition, dyskeratosis and infections (HPV) are risk factors for the development of these carcinoma. This tumour is mostly a slow growing and low grade malignancy which rarely metastasis. Early diagnosis by biopsy, especially in patients with predisposing factors, may lead to treatment and prevent the tumour from metastasizing.
