Angiokeratoma https://en.wikipedia.org/wiki/Angiokeratoma
Mae Angiokeratoma yn friw croenol anfalaen mewn capilarïau, sy'n arwain at farciau bach o liw coch i las ac wedi'i nodweddu gan hyperkeratosis. Gall angiokeratomas lluosog ar y gefnffordd mewn pobl ifanc fod yn "clwyf Fabry (Fabry disease)", anhwylder genetig sy'n gysylltiedig â chymhlethdodau systemig.

Oherwydd y prinder, gall angiokeratomas gael eu camddiagnosio fel melanoma. Gall biopsi o'r briw gynhyrchu diagnos (diagnosis) mwy cywir.

Angiokeratomas yw tyfiannau mewn pibellau gwaed, sy'n ymddangos fel pe baent wedi codi, yn goch i lympiau du a chlytiau ar y croen. Gallant ddigwydd fel briwiau sengl neu luosog, yn amrywio o ran lliw, siâp a lleoliad. Mae'r astudiaeth hon yn trafod dau achos o angiokeratoma wedi'i drin â thynnu llawfeddygol a 595‑nm Pulsed Dye Laser (PDL), gan arwain at leddfu symptomau a gwell ymddangosiad.
Angiokeratomas are vascular neoplasms with hyperkeratotic red to black papules and plaques, which may present as solitary or multiple lesions with variations in color, shape, and location. Successful treatment not only involves improvement of these symptoms but also cosmetic improvement. This report reviews 2 cases of cutaneous angiokeratoma treated with surgical excision and a 595-nm pulsed dye laser (PDL) in which the patients showed improvement of symptoms and cosmetic appearance. There are various types of angiokeratomas, and their extent, size, condition, and symptoms are different. Therefore, lesion-specific combined treatments may yield better results.
