ABSTRACT
Autosomal recessive type 2 primary hypertrophic osteoarthropathy (PHOAR2) and chronic enteropathy associated with SLCO2A1 (CEAS) are two entities caused by pathogenic variants (PVs) in the SLCO2A1 gene that can coexist or occur independently from one another. We report two cases of PHOAR2 in Mexico with concomitant CEAS and conducted a review of the literature of the reported cases of PHOAR2 and/or CEAS to analyze the relationship between their genotype and phenotype presentation. The patients from our Institution with classical PHOAR2 phenotype and CEAS, harbored SLCO2A1 c.547G > A and c.1768del variants. We reviewed 232 cases, of which 86.6% were of Asian origin, and identified 109 different variants in SLCO2A1. Intron 7, exon 13, and exon 4 were predominantly affected. The two most common PVs were c.940 + 1G > A and c.1807C > T. We found a statistically significant association between SLCO2A1 variants located in intron 7, exons 12, and 13 and the development of CEAS. Missense variants were more frequent in isolated PHOAR2, while a greater proportion of protein-truncating variants (PTVs) were found in CEAS. Further investigation is imperative to elucidate the underlying pathophysiological mechanisms associated with CEAS, thereby facilitating the identification of effective therapeutic interventions.

RESUMEN: La paquidermoperiostosis es un raro desorden hereditario caracterizado por periostosis, paquidermia y acropaquia.

ABSTRACT: Pachydermoperiostosis or primary hypertrophic osteoarthropathy, also known as Touraine-Solente-Golé syndrome, is a rare disorder, frequently inherited, characterized by periostitis of long bones,pachydermia (thickening of the skin) andacropachia. Expression tends to be variable, and so complete versions of the syndrome are infrequent. Abnormalities in fibroblast functionality have been implicated, along with an increase in collagen fibers´ synthesis.We report the case of 32-year-old man that consulted for cutaneous manifestations (thickening of face, scalp, hands and feet´s skin) since 18 years-old. We highlight the importance of the complete form of presentation and due to its similarity to other diseases.
ABSTRACT
La acropaquia es un trastorno que puede presentarse en forma aislada o formar parte del síndrome de osteoartropatía hipertrófica, entidad caracterizada por periostosis, dolor articular y acropaquia. Cuando este síndrome es causado por una mutación genética específica, se denomina osteoartropatía hipertrófica primaria. Este raro desorden hereditario se asocia, además, a alteraciones dermatológicas típicas, como hiperseborrea, acné, engrosamiento de pliegues faciales, entre otras. Una asociación rara vez descrita es la queratodermia palmoplantar. Se presenta el caso de una mujer de 46 años con osteoartropatía hipertrófica primaria asociada a queratodermia palmoplantar que asistió a la unidad de dermatología del Hospital Gustavo Fricke, Viña del Mar, Chile.
Clubbing is a disorder that can be an isolated finding or be part of the hypertrophic osteoarthropathy syndrome, an entity characterized by periostosis, joint pain and clubbing. When this syndrome is caused by a specific genetic mutation, it is called primary hypertrophic osteoarthropathy. This rare hereditary disorder is also associated with typical dermatological findings, such as hyperseborrhea, acne and facial feature coarsening. An association rarely described is palmoplantar keratoderma. We present the case of a 46-year-old woman with primary hypertrophic osteoarthropathy and palmoplantar keratoderma who came to the dermatology unit of Gustavo Fricke Hospital, Viña del Mar, Chile.

Pachydermoperiostosis or primary hypertropic osteoarthropathy is a rare hereditary disorder that was first described in 1868. It is characterized by digital clubbing, pachydermia (thickening of the facial skin and/or scalp), and periostosis (swelling of periarticular tissue and subperiosteal new bone formation). We report a case of a patient with the complete form of the disease, and with a unique appearance of the hair shaft and eyelashes. The authors propose a possible mechanism to justify the abnormalities observed in the patient's hair shafts regarding the metabolism of prostaglandins and its relationship with the hair follicle physiological cycle.
ABSTRACT
A paquidermoperiostose primária é uma doença rara, caracterizada por aposição excessiva do periósteo do crânio, coexistindo com espessamento da epiderme e derme (paquidermia), provocando deformidades grosseiras. Devido à diversidade de estruturas acometidas, há várias opções cirúrgicas e métodos complementares que são utilizados no tratamento das alterações faciais desses pacientes. Esse trabalho apresenta o lifting subperiosteal como uma opção de tratamento estético para a face de pacientes portadores dessa síndrome, através do relato de dois casos operados no Hospital das Clínicas da Universidade Federal de Minas Gerais.
Primary pachydermoperiostosis is a rare disease characterized by excessive skull affixing of the periosteum, coexisting with thickening of the epidermis and dermis (pachydermia), thereby causing gross deformities. Owing to the variety of affected structures, there are several surgical options and complementary methods that are used in the treatment of facial alterations in these patients. This report describes the use of subperiosteal detachment as an aesthetic treatment option for the faces of two patients with primary pachydermoperiostosis, operated at the Hospital das Clínicas of the Federal University of Minas Gerais.
