Placental-site trophoblastic tumor with bone metastasis: A diagnostic and therapeutic challenge.

Placental-site trophoblastic tumor (PSTT) is a rare pathological entity included in the spectrum of gestational trophoblastic neoplasia (GTN). It is a neoplasia with metastatic potential that, once metastasized, has poor prognosis because the tumor tends to be less sensitive to chemotherapy. We present a rare case of gestational trophoblastic neoplasia, in which hysterectomy for persistent gestational trophoblastic disease after hydatidiform mole, revealed a primary PSTT in the uterus.

Phyllodes tumor of the breast with actin inclusions in stromal cells: diagnosis by fine-needle aspiration cytology.

The occurrence of hyaline inclusions in stromal cells in fibroepithelial tumors of the breast is very uncommon. These inclusions, characteristic of infantile digital fibromatosis, are comprised of actin filaments. This report illustrates a case of a benign phyllodes tumor of the breast with inclusion bodies, identified by fine-needle aspiration.

Phyllodes tumor in ectopic breast tissue of the vulva.

Phyllodes tumor arising from ectopic breast tissue of the vulva is an extremely rare occurrence. A case is reported in a 34-year-old nulligravida woman, presenting as a nodule on the left labium majus. A simple excision was carried out, and no recurrence has been detected after 18 months of follow-up.

[Localized laryngeal amyloidosis. Endoscopic surgery with CO2 laser].

Laryngeal amyloidosis is a very rare disease. In the upper airways, the most common localization is the laryngeal organ, particularly the supraglotic region. Usually laryngeal amyloidosis is a localized primary form, although it has occasionally been reported in conjunction with system amyloidosis.

[Hematoma of the anterior rectus abdominis muscle as the first manifestation of lymphoproliferative disease after renal transplantation].

Rectus sheath hematoma results from the rupture of rectus muscle vessels by trauma, coagulation disorders or anticoagulant therapy, but it can occur spontaneously too. Its prognosis is good. On the other hand, posttransplant lymphoproliferative disorders (PTLD) are serious and potentially fatal complications in transplant recipients.
