Beckwith-Wiedemann syndrome, familial atypical multiple mole melanoma syndrome, and hereditary tylosis are bona fide genodermatoses with malignant potential. Each of these conditions is associated with an increased incidence of certain tumors: Wilms' tumor, adrenocortical carcinomas, pancreatoblastomas, and hepatoblastomas in Beckwith-Wiedemann syndrome; intraocular malignant melanoma, pancreatic carcinoma, and noncolorectal gastrointestinal cancers in familial atypical multiple mole melanoma syndrome; and squamous cell carcinoma of the esophagus in hereditary tylosis. Other cancer-related genodermatoses are Birt-Hogg-Dube syndrome (associated with medullary carcinoma of the thyroid and renal cell carcinoma) and its variant, Hornstein-Knickenberg syndrome (associated with colon carcinoma). Kidney tumors (Wilms' tumor and malignant rhabdoid tumor), leukemias (acute myelogenous and acute myelomonocytic), retinoblastoma, and paratesticular rhabdomyosarcoma have been reported recently in children with another genodermatosis-incontinentia pigmenti. Supernumerary nipples (polythelia) may be sporadic or familial in occurrence; their presence has been associated with an increased incidence of renal adenocarcinoma, testicular cancer, prostate cancer, and urinary bladder carcinoma. The general characteristics, mucosal and skin manifestations, and noncutaneous features of all these conditions are reviewed. Also, the associated malignancies of these genodermatoses and other conditions that are characterized by dermatologic manifestations and may be either familial or secondary to an inherited gene defect are summarized.

Rhabdomyosarcoma (RMS), the most common pediatric soft tissue sarcoma, accounts for 3% of childhood malignancies. Multiple Endocrine Neoplasia (MEN) type 2A is an autosomal dominant syndrome associated with near universal development of medullary thyroid carcinoma. We describe a previously unreported association of MEN-2A with metastatic alveolar RMS and review the literature on associated hereditary cancer predisposition syndromes and current therapeutic options. The high penetrance of malignancy in patients with MEN warrants a heightened suspicion for the development of nonendocrine malignancies. The diagnosis of RMS should prompt consideration of screening for familial genetic syndromes in certain patients.

The study was performed to determine the frequency and origin for metastatic disease to the pancreas as found in an endoscopic ultrasound directed fine-needle aspiration series. The records of the Departments of Pathology at the University of Utah School of Medicine and the David Geffen School of Medicine were electronically searched for all fine-needle aspirates obtained from pancreatic masses between January 1, 2002 and March 31, 2010. All cases with a diagnosis of metastatic disease were reviewed and whenever possible correlated with subsequent resection specimens. A total of 17 metastatic malignancies to the pancreas were detected in pancreatic FNAs representing 0.73% of all cases. Primaries included eight renal cell carcinomas, one medullary carcinoma of the thyroid, four lymphomas, one alveolar rhabdomyosarcoma, one squamous cell carcinoma derived from the esophagus, and a second squamous cell carcinoma originating from a lung primary and a small cell carcinoma of the lung. Metastatic renal cell carcinoma was the most frequent metastasis to the pancreas representing 47% of metastatic lesions detected by FNA. The metastatic deposits could be detected in the pancreas as many as 10 years following the original diagnosis and resection of the renal cell carcinoma.

The head and neck is the site of a wide and sometimes bewildering array of neuroendocrine (NE) tumors. Although recognition of NE differentiation may be necessary for appropriate tumor classification and treatment, traditional NE markers such as synaptophysin, chromogranin, and CD56 are not always sufficiently sensitive or specific to make this distinction. Insulinoma-associated protein 1 (INSM1) is a novel transcription factor that has recently demonstrated excellent sensitivity and specificity for NE differentiation in various anatomic sites, but has not yet been extensively evaluated in tumors of the head and neck. We performed INSM1 immunohistochemistry on NE tumors (n=97) and non-NE tumors (n=626) across all histologic grades and anatomic subsites of the head and neck. INSM1 was positive in all types of head and neck NE tumors evaluated here (99.0% sensitivity), including middle ear adenoma, pituitary adenoma, paraganglioma, medullary thyroid carcinoma, olfactory neuroblastoma, small cell carcinoma, large cell NE carcinoma, and sinonasal teratocarcinosarcoma. Notably, it was positive in the vast majority of high-grade NE malignancies (95.8% sensitivity). INSM1 also was negative in almost all non-NE tumors (97.6% specificity) with the highest rates of reactivity in alveolar rhabdomyosarcoma and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily B, member 1 (SMARCB1)-deficient sinonasal carcinoma. These findings confirm that INSM1 may be used as a standalone first-line marker of NE differentiation for tumors of the head and neck.
