We present a Turkish family with two cousins (OC15 and OC15b) affected with syndromic developmental delay, microcephaly, and trigonocephaly but with some phenotypic traits distinct between them. OC15 showed asymmetrical skeletal defects and syndactyly, while OC15b presented with a more severe microcephaly and semilobal holoprosencephaly. All four progenitors were related and OC15 parents were consanguineous. Read More

Adipose cells organized in small clusters under the reticular dermis closely interact with hair follicular cells and regulate the hair cycle. Intradermal adipocyte progenitor cells are activated toward the end of the telogen phase to proliferate and differentiate into mature adipocytes. These cells, surrounding the hair follicles, secrete signaling molecules that control the progression of the hair cycle. Read More

Implementation of high-resolution melting analysis of the porcupine (PORCN) gene for molecular diagnosis of focal dermal hypoplasia: Identification of a novel mutation.

J Gene Med 2020 05 16;22(5):e3165. Epub 2020 Feb 16.

Laboratory of Research in Genomics, Genetics and Bioinformatics, Hospital Infantil de México Federico Gómez, Mexico City, Mexico.

Background: Focal dermal hypoplasia (FDH) is rare X-linked dominant disease characterized by atrophy and linear pigmentation of the skin, split hand/foot deformities and ocular anomalies. FDH is caused by mutations of the Porcupine (PORCN) gene, which encodes an enzyme that catalyzes the palmitoylation of Wnt ligands required for their secretion. High resolution melting analysis (HRM) is a technique that allows rapid, labor-efficient, low-cost detection of genomic variants. Read More

Ear, Nose and Throat Surgery, Imperial College Healthcare NHS Trust, London, UK.

Goltz syndrome or focal dermal hypoplasia (FDH), is an X-linked dominant condition which predominantly involves the skin, limbs and eyes. In otolaryngology, FDH has been poorly described, but can result in increased symptoms of obstructive sleep apnoea requiring surgery. There have also been documented cases of mixed severe hearing loss secondary to congenital ossicular anomalies. Read More

Band-like Lipomatous Metaplasia of the Superficial Dermis and Nonseptate Subcutaneous Tissue: A Rare Histopathological Phenomenon With Ultrasonographic Correlation.

Am J Dermatopathol 2020 Jul;42(7):526-529

Pathology Department, Hospital Universitari General de Catalunya (HUGC), Sant Cugat del Vallès, Spain; and.

Lipomatous metaplasia of the upper dermis is a rare phenomenon scarcely described in the literature which has always been identified in the context of inflammatory or neoplastic processes. Microscopically, it should be distinguished from pseudolipomatosis cutis, dermal lipoma, nevus lipomatosus, and focal dermal hypoplasia (Goltz syndrome). This is the first report of the histologic and ultrasound evaluation of a patient with extensive involvement and the description of the coincidental finding of an anomalous nonseptate subcutaneous tissue.

Pediatr Dermatol 2020 Jan 2;37(1):217-218. Epub 2019 Aug 2.

Department of Dermatology, University of Florida, Gainesville, Florida.

Microphthalmia and linear skin defects syndrome (MLS) is a rare X-linked dominant disorder characterized by microphthalmia and linear atrophic plaques of the face and neck. The diagnosis of MLS can be challenging secondary to both its rarity and to clinical overlap with Goltz syndrome. Whereas the skin lesions of MLS are more likely to improve in appearance with age, the lesions of Goltz are typically persistent. Read More

A large number of disorders may affect the oral cavity, including genetic diseases, infections, cancers, blood diseases, skin diseases, endocrine and metabolic disorders, autoimmune and rheumatologic diseases, local lesions, to name a few. Oral mucosa shows a considerable variation in its normal structure and a wide range of conditions may affect it. Such conditions are often harmless or minor and could be primary or secondary to systemic disease. Read More

USDA/ARS Children's Nutrition Research Center, Department of Pediatrics, Baylor College of Medicine, Section of Pediatric Gastroenterology, Hepatology, and Nutrition, Texas Children's Hospital, Houston, Texas.

Focal dermal hypoplasia (FDH) is a rare genetic disorder caused by mutations in the PORCN gene located on the X chromosome. Short stature was previously noted to be a common finding in FDH, however the etiology of this is unclear. The present study sought to elucidate specific causes for short stature by assessing growth charts, determining bone ages and auxologic measurements, examining laboratory data for the common causes of growth failure, assessing dietary intake, and performing a growth hormone stimulation test.
