An immunohistochemical approach to detect oncogenic CTNNB1 mutations in primary neoplastic tissues.

Lab Invest 2018 Sep 3. Epub 2018 Sep 3.

Departments of Internal Medicine, Human Genetics, and Pathology, University of Michigan Medical School, Ann Arbor, MI, 48109, USA.

The Wnt/β-catenin signaling pathway is dysregulated in different types of neoplasms including colorectal cancer (CRC). Aberrant activation of this signaling pathway is a key early event in the development of colorectal neoplasms, and is mainly caused by loss of function mutations in Adenomatous Polyposis Coli (APC), and less frequently by β-catenin stabilization mutations via missense or interstitial genomic deletions in CTNNB1. In this study, we have defined an immunohistochemical algorithm to dissect Wnt pathway alterations in formalin-fixed and paraffin-embedded neoplastic tissues. Read More

Pilomatrixoma: A Comprehensive Review of the Literature.

Am J Dermatopathol 2018 Sep;40(9):631-641

Canniesburn Plastic Surgery Unit, Glasgow Royal Infirmary, Glasgow, United Kingdom.

Introduction: Pilomatrixoma, also known as calcifying epithelioma of Malherbe, is a superficial benign skin tumor that arises from hair follicle matrix cells. Although pilomatrixomas are well-recognized lesions, clinically they are frequently misdiagnosed as other skin conditions. By reviewing all the literature over the past 10 years, the aims of this article are to analyze the cause, clinical presentation, management, and outcome of pilomatrixoma among children and adults to gain a more complete understanding of this lesion in today's clinical context.

CDX2 and LEF-1 expression in pilomatrical tumors and their utility in the diagnosis of pilomatrical carcinoma.

J Cutan Pathol 2018 May 1;45(5):318-324. Epub 2018 Mar 1.

ProPath, Division of Dermatopathology, Dallas, Texas.

Background: The Wnt signaling pathway has been implicated in the pathogenesis of pilomatrical tumors. Lymphoid enhancer-binding factor 1 (LEF-1) is a downstream component of this pathway, and Caudal-related homeobox transcription factor 2 (CDX2) has been postulated to regulate it, but little is known about expression of these transcription factors in pilomatrical tumors.

Methods: Immunohistochemistry for CDX2, β-catenin, LEF-1, CK19, CK5, Special AT-rich sequence- binding protein 2 (SATB2), cadherin 17 and androgen receptor was performed on pilomatricomas (PMs) (N = 12), pilomatrical carcinomas (PMCAs) (N = 12) and non-pilomatrical cutaneous tumors (N = 18).

Klinik für Dermatologie, Allergologie und Phlebologie, Klinikum Bremerhaven Reinkenheide, Postbrookstr. 103, 27574, Bremerhaven, Deutschland.

A 31-year-old man developed a fast-growing tumor on the right upper arm within a black tattoo, which could be classified histologically as pilomatrixoma. While the age of the patient and the rapid growth of the tumor cannot be regarded as typical findings of pilomatrixomas, the localization on the upper arm is one of their predilection points. Despite the wide spread use of tattoos in the last few decades, tumor development in tattooed skin is rarely reported. Read More

Multiple pilomatrixomas in a survivor of WNT-activated medulloblastoma leading to the discovery of a germline APC mutation and the diagnosis of familial adenomatous polyposis.

Pediatr Blood Cancer 2018 Jan 9;65(1). Epub 2017 Aug 9.

Department of Hematology-Oncology, Children's Minnesota, Minneapolis, Minnesota.

Because children diagnosed with WNT-activated medulloblastoma have a 10-year overall survival rate of 95%, active long-term follow-up is critically important in reducing mortality from other causes. Here, we describe an 11-year-old adopted female who developed multiple pilomatrixomas 3 years after diagnosis of WNT-activated medulloblastoma, an unusual finding that prompted deeper clinical investigation. A heterozygous germline APC gene mutation was discovered, consistent with familial adenomatous polyposis. Read More

Genetic basis of calcifying cystic odontogenic tumors.

PLoS One 2017 28;12(6):e0180224. Epub 2017 Jun 28.

Department of Oral Pathology, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.

Calcifying cystic odontogenic tumors (CCOTs) are benign cystic tumors that form abnormally keratinized ghost cells. Mutations in CTNNB1, which encodes beta-catenin, have been implicated in the development of these tumors, but a causal relationship has not been definitively established. Thus, mutational hot spots in 50 cancer genes were examined by targeted next-generation sequencing in 11 samples of CCOT. Read More
