The authors report a case of ulcerovegetating lesions of the buccal mucosa in a patient with confirmed cutaneous and biological secondary syphilis, and discuss the diagnostic features of ulcerovegetating mucous syphilids which correspond to the lesion originally described by Milian, and to the diagram illustrating the work by Grinspan quoted in the references.

Epidermal nucleolar IgG deposition on direct immunofluorescence of covered normal skin was found in two patients with scleroderma and high serum concentrations of antibody to nucleolar antigen. Epidermal homogeneous and peripheral IgG deposition was also observed in two patients with systemic lupus erythematosus, antinuclear antibody of homogeneous staining pattern, but without antibody to extractable nuclear antigen. Epidermal nuclear IgG deposition in a speckled, nucleolar, homogeneous or peripheral pattern appears to correlate with high titer serum antinuclear antibody giving on immunofluorescence the same staining pattern. These immunopathologic findings cannot be considered as being specific of a subset of connective tissue disease.
Following their use of immunofluorescent methods for establishing a diagnosis in about fifteen cases of mainly inflammatory disorders of the buccal mucosa, the authors discuss the procedures used and their value in buccal bullous diseases, and also in lupus erythematosus, lichen, and aphthosis.

We studied a bullous photodermatosis recurring for two years in a old woman. The eruption was diagnosed as a pellagra-like syndrome on tryptophan loading test disorders without any other cause of sun sensitivity. The static and dynamic metabolic investigation was centered on tryptophan and vitaminic coenzymes which mediate catabolic reactions. The defect are located on the kinurenin pathway. The discussion analyses the possible relations between the dermatosis and the biological disturbances observed.
A new case of this unusual entity is reported. The patient, male aged 43 has an hypertrophy of the first and second left fingers. Radiographic examination shows bony overgrowth and marked soft tissue thickening. Arteriography did not show any evidence of angioma or arteriovenous fistula. Histologic examination shows deposits of fat in soft tissue thickening. Macrodystrophia lipomatosa is a rare disease, usually confined to one or two digits of the hand, and sometimes of the foot. A dysembryoplasic aetiology could be sustained, and this entity is very close from others bone or soft-tissue hamartomas.
The authors report two cases of Grover's transient acantholytic dermatosis. These two cases exhibit some unusual features. Case no. 1 is that of a 39-year-old female with typical lesions on chest, neck, back and upper limbs. The course was cyclic with spontaneous regressions. This condition had been present for 4 years. Case no. 2 was that of a 46-year-old man with a large erythemato-squamous plaque of the left chest wall exhibiting a vesicular lining. In both instances the histologic findings revealed a picture similar to that of Hailey-Hailey's familial benign pemphigus. In spite of these unusual data, long duration and atypical clinical aspects, these two cases are consistant with the diagnosis of Grover's disease as evidenced by description found in the literature.
