[Cystic lymphangioma of the supraclavicular and right axillary fossae]. / Naczyniak limfatyczny torbielowaty dolu nadobojczykowego i pachowego prawego.

Five years ago, in a 34-year-old female patient a tumour developed in the right supraclavicular fossa which gradually increased in size. A few months ago she had noticed also a tumour in the axillary fossa on the same side. On physical examination, USG, and contrast X-ray it was found that it was a cyst of hour-glass shape (narrowing of retro-clavicular). The cyst was removed totally. Histological examination: cystic lymphangioma (hygroma). The aetiology, diagnosis, and treatment of this type of tumours are discussed.
