    Notes: Abstract Three patients with a sporadic form of multiple endocrine neoplasia (MEN) IIb are presented. MEN IIb is the association of medullary carcinoma of the thyroid (MTC), pheochromocytoma and multiple mucosal neuromata. The age at diagnosis and primary therapy of MTC was relatively late (8, 16, 18 years) although thyroid enlargement (two cases), typical marfanoid habitus (two cases) or multiple mucosal neuromata (one case) had been evident since early childhood. The diagnosis was confirmed by measurements of tumour markers like calcitonin (CT) and carcinoembryonic antigen (CEA) for MTC, measurements of vanillylmandelic acid for pheochromocytoma, evaluation of the thyroid gland by sonography, scintigraphy and fine needle biopsy, and investigation of the adrenals by computer tomography and meta-(I-131) iodobenzylguanidine (I-131-MIBG) scintigraphy. After surgical treatment determinations of tumour markers confirmed relapses of MTC in all cases. Early diagnosis of MEN IIb, which could be made by recognition of the typical clinical appearance, is of special importance because of the poor prognosis of MTC.

    Description / Table of Contents: Zusammenfassung Am Krankengut von 44 Patienten wird die Zunahme der Incidenz und der Anteil familiärer, vor allem „occulter” Carcinome, die schon in jugendlichem Alter diagnostiziert werden können, beschrieben. Die frühe Diagnose ist entscheidend, da LK-Metastasierung häufig und früh erfolgt und einen entscheidenden prognostischen Faktor darstellt. Wichtige diagnostische Hilfsmittel bei Screening und Follow-up sind neben dem Calcitonin-Stimulationstest die Sonographie, das CT und die selektive Venenkatheterisierung. Ein MEN II-Syndrom sollte präoperativ bekannt sein. Das chirurgische Therapiekonzept orientiert sich am sporadischen bzw. familiären TU und bei letzterem am unterschiedlich frühen Tumorstadium. Es schließt auch bei occultem TU stets eine angemessene Lymphknotendissektion ein.
    Notes: Summary A review of the case histories of 44 patients showed an increasing incidence of C-cell carcinoma with an increasing amount of “occult” familiary tumors diagnosed at young age. Early diagnosis is important: lymph node metastases, which occur frequently and early, are decisive with regard to prognosis. The important diagnostic methods for family screening, sporadic (palpable) tumors and follow-up are stimulation of s-calcitonin (Pentagastrin), ultrasonography, CMT and selective venous catheterization. The presence of an MEN II syndrome should be known preoperatively. Surgical strategy has to take into account the differences between sporadic and familiary tumors and early stages in the familiary form. In occult tumors total thyroidectomy should also be performed together with an appropriate lymph node dissection.
