Metastasis to skin sites is an uncommon feature of SCCHN. SM may represent the first clinical evidence of impending loco-regional recurrence or distant metastasis. The development of SM is an ominous sign associated with an extremely poor prognosis, similar to the development of distant metastasis at more typical sites. Both the development of SM and survival of patients developing SM are independent of primary tumor stage. Current treatment options of SM are limited in their efficacy.

Our findings provided support for synchronous, albeit distinct, primary tumors in the ovary and cervical thyroid. "Field cancerization" and early genomic instability may explain multifocality in all thyroid-type tissue. In this regard, patients with malignant struma ovarii should undergo imaging of their thyroid gland for coexisting disease and thyroidectomy recommended for suspected malignancy or in preparation for radioiodine therapy.

We describe an infant with the Neu-Laxova syndrome. Some new guidelines for syndrome identification are presented, using this syndrome as an example.
