[Diagnostic and therapeutic problems posed by a congenital lateral fistula of the neck (author's transl)].

Cysts and congenital lateral cervical fistulas are related to the persistance of the normally transitory branchial pouches and their embryologico-anatomic arrangement. Due to this fact they have a preferential topography. An atypical fistula of the second branchial cleft is reported. It is a congenital supra-hyoidian lateral cervical fistula with an intra-parotid route which terminates in the tonsils. The extreme variability of the external orifice, the pathogenic nature of the internal orifice and of the fistular route, as well as the initial discovery of the facial nerve and tonsillectomy in lateral fistulas of the neck are, by the same occasion, brought to mind.

[Kaposi's sarcoma simulating a splenolymphatic lymphoma, toxoplasmosis, and terminal cryptococcus infection (author's transl)].

The authors report a case of Kaposi's sarcome (K.S.) characterized by the small degree of cutaneous involvement as opposed to splenic and lymphatic invasion, lymphoplasmocytic infiltration of the bone marrow, and opportunistic infections (toxoplasmosis, and cryptococcosis). The rapid mortal outcome and the anatomoclinical characteristics of the K.S. enable this case to be classified as one of the rare types of malignant K.S. with pseudo-cryptoccosis features.

[Crosti's reticulosis. Report on three cases, one with ultrastructural study (author's transl)].

Crosti's reticulosis is defined as a peculiar form of well-circumscribed, slow developing lymphomas in adults, with a malignant histological picture. Three cases with typical dorsal localisation according to Crosti's first description are reported and the cardinal features of this type of tumour are recalled. One observation includes an ultrastructural study which confirms the malignant nature of histiocytes in this disease. Localisation in back seems not to be exclusive and a study of 32 cases of the literature about other localised cutaneous reticulum cell lymphomas show them similar to Crosti's reticulosis-which authorizes their classification, as was proposed by Thiers in a single group of slow developing circumscribed reticuloses.

[Reye's syndrome: pathological study of 2 cases].

The authors report two personal cases of Reye's syndrome, one of which was studied by electron microscopy, and comment on the pathological characteristics of this disease. The hepatic lesions are most important and resemble fatty degeneration rather than simple steatosis. This notion is confirmed by data obtained by electron microscopy which revealed marked abnormalities of the cellular organites, in particular, mitochondria. The nervous involvement included mainly, oedema of the nerve sheath. These facts emphasize the importance of metabolic disturbances in the physiopathology of the disease.
