CASE 811: ADOLESCENT PHYLLODES TUMOR (PT) and a REVIEW of P T in VMU, Dr PHAN THANH HẢI, Dr TRƯƠNG THỊ NGỌC TIẾN, Dr TRƯƠNG THỊ MỸ HOÀNG, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 A 14 year-old female adolescent with a right breast tumor rapid progressing bigger for 4 months.

Breast ultrasound assessment was classified BI-RADS 4. Mixed tumor with cystic and solid parts, hypervascular, micro calcified, irregular border, spiculated margin. Biopsy result was benign phyllodes tumor.

But the result of histoimmunologicostaining was a malignant phyllodes tumor.

Phyllodes tumor is rare in adolescent. Only 20 cases were published in litterature. 

Two cases in adolescent [one 15 yo, another 14 yo] were published on our VMU.

In women, there were 11 cases of phyllodes tumor published on our VMU. Phyllodes tumor (1-3% breast tumor) comes from the fibrous tissue, 27 % malignant, growing rapidly with large size [ > 20 cm]. 

PTB is a very rare breast tumor in women aged 35 to 55 years. Our patient is younger but the progress of the tumor is the same in the literature: "unilateral, nodular, painless mass which has a history of the mass but that grows rapidly in the short term".

Phyllodes tumors (or phylloides tumors) are rare breast tumors that start in the connective (stromal) tissue of the breast, not the ducts or glands (which is where most breast cancers start). Most phyllodes tumors are benign and only a small number are malignant (cancer). American Cancer Society, July 2022.
