BACKGROUND:

Sarcomatoid cutaneous epidermoid cancer is a rare neoplasm, with a low risk of malignancy and less than 2% risk of metastasis. Its aggressive behavior is unusual and almost always associated with factors favoring its malignancy. Placental metastasis is also exceptional: only 61 cases have been reported to date.

CLINICAL CASE:

35-year-old female patient, with a history of two pregnancies, in 33 weeks of gestation, infiltrating squamous cell carcinoma of the left leg, with supracondylar amputation and pulmonary metastasis. She was admitted to the emergency room for respiratory distress, without labor, tachycardic and tachypneic. It was decided to perform a cesarean section with live birth, female, 1860 g, without complications. After the intervention, the patient was transferred to an institution specialized in oncologic care, where she died 24 hours later. The newborn was discharged without complications and without oncologic or other manifestations up to one year of age.

CONCLUSIONS:

After an exhaustive search of the literature, the authors consider the case reported here to be the first case of sarcomatoid epidermoid skin cancer with metastasis to the placenta.
