Macrodactyly, defined as enlargement of one or several digits of the hands or feet, is a rare malformation. It may be due tumorous enlargement of a single tissue element, as in hemangioma, lymphangioma or enchondroma or it may be caused by overgrowth of all structures of the digit, including phalanges, subcutaneous tissue, nerves, vessels and skin as in ‘true macrodactyly’(Barsky, 1967). Furthe...

Proteus syndrome is a rare congenital disorder comprised of subcutaneous and internal hamartomas, miscellaneous skin and vascular nevi, skeletal and nervous system and eye malformations, with characteristic manifestations including hemihypertrophy, local gigantism, macrodactyly and cerebriform thickness of soles and palms. A 23 year-old man with diagnosis of proteus syndrome had sever ane...

BACKGROUND Lipofibromatous harmartoma (LFH) is a rare tumour that requires early diagnosis and treatment. To alert physicians to the possibility of this tumour, we review the epidemiologic and pathological characteristics, the presentation, diagnosis and treatment of LFH in the upper extremity. METHODS We obtained data from a MEDLINE search of the English literature from 1966 to June 2003, us...

Proteus syndrome (PS) is a rare and sporadic disorder characterized by overgrowth of multiple tissues and a propensity to develop particular neoplasms. The clinical manifestations of PS include macrodactyly, vertebral abnormalities, asymmetric limb overgrowth and length discrepancy, hyperostosis, abnormal and asymmetric fat distribution, asymmetric muscle development, connective tissue nevi, an...

Isolated macrodactyly (OMIM 155500) belongs to a heterogeneous group of overgrowth syndromes. It is a congenital anomaly resulting in enlargement of all tissues localized to the terminal portions of a limb and caused by somatic mutations in the phosphatidylinositol 3-kinase catalytic alpha (PIK3CA, OMIM 171834) gene. Here we report a Hungarian girl with macrodactyly and syndactyly. Genetic scre...
