Follicular thyroid carcinoma metastatic to skin: a small papule and a big diagnostic change.

An Bras Dermatol 2019 Jan-Feb;94(1):76-78

Department of Pathology, Laboratório Bacchi, Botucatu (SP), Brazil.

Cutaneous metastases are uncommon in daily practice, although very important, since they may be the first manifestation of an undiscovered primary neoplasm or the first indication of recurrence. Cutaneous metastases from the breast are the most frequent in women and cutaneous metastases from the lung are the most frequent in men. Thyroid carcinoma, despite representing the most frequent endocrine neoplasm, is considered a rare neoplasm, corresponding to 1% of malignant neoplasms diagnosed. Read More

CyberKnife® Radiosurgery as First-line Treatment for Catastrophic Epilepsy Caused by Hypothalamic Hamartoma.

Cureus 2018 Jul 12;10(7):e2968. Epub 2018 Jul 12.

Cyberknife Center, Centro diagnostico italiano, Milano, ITA.

Hypothalamic hamartomas (HH) are deep-seated lesions often associated with catastrophic epilepsy (an epileptic syndrome characterized by severe, drug-refractory seizures eventually leading to mental retardation and death). Radical microsurgical resection is not feasible for lesions located within the wall of the third ventricle inside the hypothalamus. Frame-based stereotactic radiosurgery has been reported as an effective treatment modality for small- to medium-size intrahypothalamic hamartomas, providing excellent seizure outcomes without lasting complications.

hamartoma tumour syndrome (PHTS) is a heterogeneous group of rare, autosomal dominant disorders associated with germline mutations. PHTS patients routinely develop hamartomas, which are benign tissue overgrowths comprised of disorganized 'normal' cells. Efforts to generate PHTS animal models have been largely unsuccessful due to the early lethality of homozygous germline mutations in , together with the lack of hamartoma formation in most conditional mutants generated to date.

Novel mutations in the ciliopathy-associated gene CPLANE1 (C5orf42) cause OFD syndrome type VI rather than Joubert syndrome.

Eur J Med Genet 2018 Oct 30;61(10):585-595. Epub 2018 Mar 30.

Kariminejad-Najmabadi Pathology & Genetics Center, Tehran, Iran.

Mutations in CPLANE1 (previously known as C5orf42) cause Oral-Facial-Digital Syndrome type VI (OFD6) as well as milder Joubert syndrome (JS) phenotypes. Seven new cases from five unrelated families diagnosed with pure OFD6 were systematically examined. Based on the clinical manifestations of these patients and those described in the literature, we revised the diagnostic features of OFD6 and include the seven most common characteristics: 1) molar tooth sign, 2) tongue hamartoma and/or lobulated tongue, 3) additional frenula, 4) mesoaxial polydactyly of hands, 5) preaxial polydactyly of feet, 6) syndactyly and/or bifid toe, and 7) hypothalamic hamartoma.

Cowden syndrome is a rare genodermatosis of autosomal dominant inheritance characterized by multiple hamartomas in several organs and an increased risk of malignancies. We present the case of a 53-year-old man with a history of benign and malignant thyroid disease, intestinal polyposis, and Chiari malformation. He had several trichilemmomas, papillomatosis of the oral cavity, macular pigmentation of the glans penis, among other clinical features suggestive of Cowden syndrome. Read More

INTU-related oral-facial-digital syndrome type VI: A confirmatory report.

Clin Genet 2018 Jun 6;93(6):1205-1209. Epub 2018 Apr 6.

Department of Genetics, APHP-Robert Debré University Hospital, Paris, France.

Oral-facial-digital (OFD) syndromes are a subgroup of ciliopathies distinguished by the co-occurrence of hamartomas and/or multiple frenula of the oral region and digital anomalies. Several clinical forms of OFD syndromes are distinguished by their associated anomalies and/or inheritance patterns, and at least 20 genetic types of OFD syndromes have been delineated. We describe here a child with preaxial and postaxial polydactyly, lingual hamartoma, a congenital heart defect, delayed development and cerebellar peduncles displaying the molar tooth sign.

Hemimegalencephaly with Bannayan-Riley-Ruvalcaba syndrome.

Epileptic Disord 2018 Feb;20(1):30-34

Division of Medical Genetics, Department of Pediatrics, Duke University, Durham, USA.

Hemimegalencephaly is known to occur in Proteus syndrome, but has not been reported, to our knowledge, in the other PTEN mutation-related syndrome of Bannayan-Riley-Ruvalcaba. Here, we report a patient with Bannayan-Riley-Ruvalcaba syndrome who also had hemimegalencephaly and in whom the hemimegalencephaly was evident well before presentation of the characteristic manifestations of Bannayan-Riley-Ruvalcaba syndrome. An 11-year-old boy developed drug-resistant focal seizures on the fifth day of life. Read More

J Pediatr Orthop 2018 Mar;38(3):e138-e144

Children's National Health System, NW, Washington, DC.

Introduction: Proteus syndrome (PS) is a rare mosaic disorder comprising asymmetric bony and soft tissue overgrowth leading to significant morbidity. Placement of growth inhibition hardware with subsequent epiphyseal arrest improves leg-length and angular deformities in pediatric patients without PS. The purpose of this study was to review the surgical approach and present outcomes, complications, and recommendations in 8 patients with PS and leg-length discrepancy (LLD). Read More

Germline Mutations and the Basaloid Follicular Hamartoma Values in the Tumor Spectrum of Basal Cell Carcinoma Syndrome (NBCCS).

Anticancer Res 2018 01;38(1):471-476

Dermatology Unit, Surgical, Medical and Dental Department of Morphological Sciences related to Transplant, Oncology and Regenerative Medicine, University of Modena and Reggio Emilia, Modena, Italy.

Background/aim: Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominantly inherited disorder characterized by multiple basal cell carcinomas (BCC), odontogenic tumors and various skeletal anomalies. Basaloid follicular hamartomas (BFHs) constitute rare neoplasms that can be detected in sporadic and familial settings as in the Basaloid Follicular Hamartoma Syndrome (BFHS). Although BFHS shares clinical, histopathological and genetic overlapping with the NBCCS, they are still considered two distinctive entities. Read More

Department of Pathology, The Johns Hopkins University School of Medicine, Baltimore, MD, United States.

Colorectal cancer (CRC) accounts for over 8% of all deaths annually worldwide. Between 2 and 5% of all CRCs occur due to inherited syndromes, including Lynch syndrome, familial adenomatous polyposis, MUTYH-associated polyposis, Peutz-Jeghers syndrome, juvenile polyposis and Cowden/PTEN hamartoma syndrome. In addition, serrated polyposis is a clinically defined condition characterised by multiple colorectal serrated polyps and an increased risk of CRC but the genetics are not known. Read More

Broad spectrum of neuropsychiatric phenotypes associated with white matter disease in PTEN hamartoma tumor syndrome.

Am J Med Genet B Neuropsychiatr Genet 2018 Jan 20;177(1):101-109. Epub 2017 Nov 20.

Department of Genetics, Children's Hospital of Eastern Ontario, Ottawa, Ontario, Canada.

White matter lesions have been described in patients with PTEN hamartoma tumor syndrome (PHTS). How these lesions correlate with the neurocognitive features associated with PTEN mutations, such as autism spectrum disorder (ASD) or developmental delay, has not been well established. We report nine patients with PTEN mutations and white matter changes on brain magnetic resonance imaging (MRI), eight of whom were referred for reasons other than developmental delay or ASD.
