We are presenting a rare case of a 71-year-old Filipino female with the presence of two skin cancers occurring simultaneously in two different regions of the body.

Patient noted symmetrical, erythematous, pruritic, eczematous patches and plaques on her inguinal areas five years prior to consultation. The patient also had a 2-year history of multiple pigmented papules and plaques on the forehead, left jaw, right cheek, lateral canthus of the left eye, and sternal area associated with occasional bleeding.

Skin examination showed symmetrical, irregularly shaped bright red moist plaques with finger-like projections measuring 26 cm x 9 cm on the vulva, inguinal areas, and intergluteal areas. The patient also had multiple pigmented papules and plaques with rolled borders located on the right forehead, lateral canthus of the left eye, right cheek, left jaw, and sternal area with measurements ranging from 0.3 x 0.4 cm to 1.5 x 2.0 cm in size.

Histological examination of the vulvar skin biopsy is signed out as extramammary Paget’s disease with positive immunohistochemical stain for Cytokeratin 7. A skin punch biopsy on the pigmented plaque on the right forehead is signed out as basal cell carcinoma.

This is the first known case of the simultaneous occurrence of extramammary Paget’s disease and basal cell carcinoma on different regions of the body. We speculate that the two tumors in our patient may have developed independently with no causal relationship, but we are attributing the occurrence of the patient’s carcinomas to her old age, prolonged sun exposure, and immunosuppression.
