“…Tissue pigmentation in domestic animals can be caused by exogenous substances, such as carotenoids, or by endogenous substances, as occurs in certain genetic diseases (JONES et al, 1997;VARASCHIN et al, 1998). In Colombia, the consumption of the plants Bunchosia pseudonitida and Bunchosia armeniaca cause pigmentation of different tissues in cattle and sheep (GÁMEZ et al, 1983a, b associated with the consumption of Acacia aneura (WINTER, 1961;JONES et al, 1997).…”

“…Type II photosensitization is associated with genetic disorders that compromise the metabolism of the heme pigment (Mauldin & Peters-Kennedy 2016, Varaschin et al 1998. This disorder results in the accumulation of hematoporphyrins in tissues (Mauldin & Peters-Kennedy 2016).…”

Shapes of pathology

The shape is one of the key features of a lesion and a pathologist must be able to identify and interpret these forms in the context of any gross and microscopic changes. One of the principles of adult learning is to engage the learner with previously understood information. If, when presenting material that is new, a connection with something the student already has familiarity with, the learning process is accelerated. As the learners are already familiar with shapes they have encountered throughout their pre-pathology learning, these can be used to hasten the incorporation and understanding of lesions. This paper describes various shapes that are used in describing lesions in veterinary pathology.

Case Report: A Possible Case of Congenital Erythropoietic Porphyria in a Gir Calf: A Clinical, Pathological, and Molecular Approach

Congenital erythropoietic porphyria (CEP) is a rare hereditary autosomal recessive disease which has never been reported in Zebu cattle. A 3-day-old Gir calf showed teeth discoloration, fever, dehydration, and dyspnea. The main gross findings were pink-colored teeth, red-brown periosteum and bone marrow, and a fluorescent bright pink coloration of the bone marrow and articular surfaces under ultraviolet light. Aggregates of periodic acid-Schiff (PAS)-stained porphyrin pigments were evident in the lungs, kidneys, and the liver. An intron 8 single-nucleotide polymorphism (SNP) in both the Gir calf and control animals, along with the absence of the uroporphyrin III synthetase (UROS) gene mutation, was observed. Most SNPs were located in the intron regions of the UROS gene without relevance for CEP. A continuous loss of genetic variability and an increase in inbreeding in some herds may be related to CEP in Gir cattle, one of the most prominent Zebu breeds worldwide. In summary, this study describes a presumptive case of CEP in a Gir calf based on clinical and pathological findings. A definitive diagnosis would require the measurement of porphyrin levels in blood, urine, or tissues or the identification of UROS gene defects.
