Pyoderma gangrenosum is a very rare and aseptic ulcerative dermatosis with neutrophilic infiltration. It's often associated with a chronic or systemic disease. The diagnosis is clinical. It's a diagnosis of exclusion. It often mimics other diseases. The diagnosis is made later especially in gynecology-obstetric. That's why we should not miss the diagnosis because the course is unpredictable and can be fatal. Here we present a case of a 23 years old woman who presents a skin lesion in the right breast and a recurrence during pregnancy after the caesarean. The evolution was fatal, and the patient, unfortunately, died a few weeks later.

Phyllode breast tumor is a rare and very acute disease. The diagnosis is very hard, and histology is still the key to diagnosis. Conservative treatment with good margin excision is the gold standard. The exophytic form is rare and always malign. Here, we present a 39 years old woman with an exophytic phyllode breast tumor who had a large conservative treatment. The histopathology revealed a benign phyllode tumor grade 1. The particularity of our patient is the benignant form of this exophytic tumor without metastasis and the recurrence of the tumor after the conservative treatment.

The giant mucinous cystadenoma is a rare ovarian neoplasm with benign biological behavior, characterized by a large tumor volume. Delayed diagnosis can cause serious complications such as rupture, infection and malignant transformation. In this article, and based on literature review, we will discuss the case of a giant mucinous cystadenoma in a 54-yearold woman treated surgically by a total hysterectomy with bilateral adnexectomy.
