Many autofluorescent cells, rich in yellow pigment are described in the rabbit's sacculus rotundus. This pigment stained positively with Sudan black, PAS and Masson-Hamperl techniques. The cells correspond to those described in rat and in mice lymphatic organs. The possible origin of the pigment is discussed.
The GRO1 oncogene (melanoma growth-stimulating activity alpha) has been localized in region 4q21. The involvement of this chromosomal region in clonal aberrations found in primary melanoma cell cultures could have an important role in the etiology and pathogenesis of this tumor. We characterized three primary cell cultures obtained from different patients, each of which showed clonal chromosomal aberrations involving the 4q21 region.
Verruciform xanthoma is a solitary verrucous lesion, usually occurring on the oral mucosa. It is characterized histologically by the presence of foam cells within elongated dermal papillae.
