Article Type: Case Report | First Published: 2024/05/31
Extramedullary presentation of acute undifferentiated leukemia is uncommon, and it is unclear if this is an initial manifestation of a subsequent systemic disease. We present a 67-year-old Caucasian female with skin lesions and multiple enlarged lymph nodes. Microscopy showed diffuse leukemic infiltrates, positive for dim CD45, CD34, CD117, TdT, CD56 and CD43, but negative for HLADR, MPO, CD4, CD68, CD3, CD4, CD20, CD19, and CD79a. We discuss the differential diagnosis of acute undifferentiated ...

Kaposi sarcoma (KS) is a tumor originating from endothelial cells, both vascular and lymphatic, and is associated with human herpesvirus 8 (HHV-8). Four distinct KS subtypes have been defined: Classic, endemic, iatrogenic, and epidemic or acquired immunodeficiency syndrome (AIDS)-related KS. A fifth subtype has more recently been recognized in men who have sex with men (MSM) in the absence HIV infection. We report here on three cases of KS in HIV-negative MSM and review the literature. Two patie...

This is the most common neutrophilic dermatosis and the prototype of superficial dermal acute neutrophilic dermatoses. Its incidence is rare. Sweet's syndrome predilection is for adults aged 30 to 50, but children have also been reported. There is a female predilection [1]. It is distributed worldwide, with no racial predilection. The typical picture is of a sudden-onset rash, accompanied by high fever and neutrophilic leukocytosis [2]. Recombinant granulocyte-colony stimulating factor (G-CSF) h...

Mycosis fungoides and its variants account for almost 50% of all cutaneous lymphomas and around 65% of cutaneous T-cell lymphomas. We report the clinical case of a patient with a tumoral nodule, with progressive evolution and rapid transformation. Our patient was undergoing chemotherapy. After mycosis fungoides, CD30+ cutaneous lymphoproliferations are the most frequent pathologies among cutaneous T-cell lymphomas, accounting for 20% of this group....

Paraneoplastic pemphigus is a very rare disease. However, it has been described in many countries. It most often affects middle-aged adults, but a few pediatric cases have also been reported. We report the clinical case of a patient being followed for colon cancer who developed erythematous plaques topped by clear and hemorrhagic bullae. Our patient was undergoing treatment with oral corticosteroids and chemotherapy. Paraneoplastic pemphigus was first described in 1990. Since then, numerous case...
