ABSTRACT
Marked prognostic differences exist between the two cutaneous lesions: squamous cell epithelioma and keratoacanthoma. The former may affect the vital prognosis while the latter usually heals spontaneously. Early diagnosis is therefore of the utmost importance, but clinico-pathologic discordances can exist when a first intention partial biopsy does not provide histologic data essential for diagnosis, or as a result of misleading clinical forms. Wide excision of these lesions is therefore an immediate necessity.

Oriental Sore is the dry cutaneous form of leishmaniasis, a parasitic infection common to man and to certain vertebrates and transmitted by insects: the phlebotomes. This benign tropical disease exists in South East France where it remains very rare, human contamination always being accidental. The lesions, single or multiple, affect the skin only. On the face, the differential diagnosis arises with other much commoner cutaneous lesions (impetigo, etc.). They consist, after 2 to 4 months of incubation, of a rounded erythematous papule, neither pruritic nor painful, which becomes secondarily excavated to produce a crusted ulcer. This lesion, typical at this stage, then persists for many months before an unsightly scar develops. Treatment is local: surgical excision offering the possibility of histological examination and hence a diagnosis. Plastic surgery may be used to correct scars in advanced forms.

An atypical feature of a further case of salivary calcinosis reported was its exclusively unilateral parotid site. The clinical appearance was that of a pseudo-tumor following a long period of a spontaneously regressive unilateral parotid swelling. The co-existence of a Gougerot-Sjögren syndrome was confirmed clinically by the presence of a xerostomia, and radiologically by suggestive signs after a parotid sialogram. Immunological features were atypical in nature.
