Painful tumors of the skin: "CALM HOG FLED PEN AND GETS BACK".

Clin Cosmet Investig Dermatol 2019 13;12:123-132. Epub 2019 Feb 13.

Compass Dermatopathology, San Diego, CA, USA.

Painful tumors of the skin present as dermal or subcutaneous nodules. They can originate from several sources: adipose tissue, cartilage degeneration, deposition of bone or calcium, eccrine glands, fibrous tissue, infiltration of benign (endometrium) or malignant (metastatic neoplasm) tissue, muscle, nerve, or vascular structures. Although pathologic evaluation of the lesion is necessary to determine the diagnosis, it is possible to make a reasonable differential diagnosis based on knowledge of prior tumors that have appeared as tender lesions.

Oral Diagnostic Sciences Department, Division of Oral and Maxillofacial Radiology, Faculty of Dentistry, King Abdulaziz University, P.O. Box 21589, Jeddah, Saudi Arabia.

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization. Read More

From pseudohypoparathyroidism to inactivating PTH/PTHrP signalling disorder (iPPSD), a novel classification proposed by the EuroPHP network.

Eur J Endocrinol 2016 Dec 11;175(6):P1-P17. Epub 2016 Jul 11.

APHPReference Center for rare disorders of the Calcium and Phosphate Metabolism, filière OSCAR and Plateforme d'Expertise Maladies Rares Paris-Sud, Hôpital Bicêtre Paris Sud, Le Kremlin Bicêtre, France

Objective: Disorders caused by impairments in the parathyroid hormone (PTH) signalling pathway are historically classified under the term pseudohypoparathyroidism (PHP), which encompasses rare, related and highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and the results of an in vitro assay to measure Gsa protein activity. However, this classification disregards other related diseases such as acrodysostosis (ACRDYS) or progressive osseous heteroplasia (POH), as well as recent findings of clinical and genetic/epigenetic background of the different subtypes.

Osteoma cutis is a condition that generally presents with true bony deposits in the skin. Although the pathogenesis of osteoma cutis is not clear, it supposes that certain preexisting conditions like acne vulgaris may contribute to generating these ossifications. These osteomas are usually asymptomatic and do not require any treatment unless they cause cosmetic issues. Read More

Pseudohypoparathyroidism and Gsα-cAMP-linked disorders: current view and open issues.

Nat Rev Endocrinol 2016 Jun 22;12(6):347-56. Epub 2016 Apr 22.

Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Endocrinology Unit, Department of Clinical Sciences and Community Health, University of Milan, Via Francesco Sforza 35, Milan 20122, Italy.

Pseudohypoparathyroidism exemplifies an unusual form of hormone resistance as the underlying molecular defect is a partial deficiency of the α subunit of the stimulatory G protein (Gsα), a key regulator of the cAMP signalling pathway, rather than of the parathyroid hormone (PTH) receptor itself. Despite the first description of this disorder dating back to 1942, later findings have unveiled complex epigenetic alterations in addition to classic mutations in GNAS underpining the molecular basis of the main subtypes of pseudohypoparathyroidism. Moreover, mutations in PRKAR1A and PDE4D, which encode proteins crucial for Gsα-cAMP-mediated signalling, have been found in patients with acrodysostosis. Read More

Progressive osseous heteroplasia (POH) is a segmental disorder characterized by progressive heterotopic ossification that extends from dermal and subcutaneous tissues to deeper structures. So far, it has been taken as a rarely occurring bone disease with autosomal dominant inheritance. Here, arguments are presented in favor of the alternative concept that the disorder is merely a type 2 segmental manifestation of autosomal dominant GNAS inactivation disorders. Read More

Acne vulgaris (AV) is considered a straightforward diagnosis made clinically without specific diagnostic testing. However, certain disorders may simulate AV, such as multiple small epidermal cysts or deep milia, multiple osteoma cutis, multiple small adnexal neoplasms, and follicular and/or infections characterized by multiple small papules and/or pustules such as gram-positive folliculitis, gram-negative folliculitis, Malassezia folliculitis, keratosis pilaris, and flat warts. This can lead to an erroneous diagnosis and improper management. Read More

Reports of patients with mild POH with Albright hereditary osteodystrophy (AHO), specifically pseudohypoparathyroidism type Ia (PHP Ia) with hormonal resistance, suggest the possibility of a common molecular basis. GNAS has been implicated to account for overlapping features of POH and PHP Ia. Read More

Progressive osseous heteroplasia: diagnosis, treatment, and prognosis.

Appl Clin Genet 2015 30;8:37-48. Epub 2015 Jan 30.

Progressive osseous heteroplasia (POH) is an ultrarare genetic condition of progressive ectopic ossification. Most cases of POH are caused by heterozygous inactivating mutations of GNAS, the gene encoding the alpha subunit of the G-stimulatory protein of adenylyl cyclase. POH is part of a spectrum of related genetic disorders, including Albright hereditary osteodystrophy, pseudohypoparathyroidism, and primary osteoma cutis, that share common features of superficial ossification and association with inactivating mutations of GNAS.

Plate-like osteoma cutis.

Dermatol Online J 2014 Dec 16;20(12). Epub 2014 Dec 16.

New York University School of Medicine.

Osteoma cutis is the aberrant development of bone within the skin. The bone formation may be de novo (primary) or result from an injury to the skin (secondary). Here we present a healthy 53-year-old man with no known abnormalities in calcium or phosphate metabolism with plate-like osteoma cutis of the scalp. Read More

GNAS mutations in Pseudohypoparathyroidism type 1a and related disorders.

Hum Mutat 2015 Jan 28;36(1):11-9. Epub 2014 Nov 28.

CICS-UBI, Health Sciences Research Centre, Faculty of Health Sciences, University of Beira Interior, Covilhã 6200-506, Portugal.

Pseudohypoparathyroidism type 1a (PHP1a) is characterized by hypocalcaemia and hyperphosphatemia due to parathyroid hormone resistance, in association with the features of Albright's hereditary osteodystrophy (AHO). PHP1a is caused by maternally inherited inactivating mutations of Gs-alpha, which is encoded by a complex imprinted locus termed GNAS. Paternally inherited mutations can lead either to pseudopseudohypoparathyroidism (PPHP) characterized by AHO alone, or to progressive osseous heteroplasia (POH), characterized by severe heterotopic ossification.

Identification of a novel mutation in a patient with pseudohypoparathyroidism type Ia.

Korean J Pediatr 2014 May 31;57(5):240-4. Epub 2014 May 31.

Department of Pediatrics, Hallym University College of Medicine, Chunchon, Korea.

Pseudohypoparathyroidism type Ia (PHP Ia) is a disorder characterized by multiform hormonal resistance including parathyroid hormone (PTH) resistance and Albright hereditary osteodystrophy (AHO). It is caused by heterozygous inactivating mutations within the Gs alpha-encoding GNAS exons. A 9-year-old boy presented with clinical and laboratory abnormalities including hypocalcemia, hyperphosphatemia, PTH resistance, multihormone resistance and AHO (round face, short stature, obesity, brachydactyly and osteoma cutis) which were typical of PHP Ia.
