Skin lesions in chronic lymphocytic leukemia (CLL) have been reported in between 4% and 20% of patients with CLL and are a rare entity compared with T-cell leukemia. They can present mainly as leukemic cutis or, frequently, as secondary lesions such like urticaria, itching, pyoderma gangrenosum, cutaneous vasculitis, Sweet’s syndrome, and erythroderma. We report on an adult patient who developed a skin lesion of forearms and hands, leading to the discovery of isolated cutaneous CLL after two biopsies. Isolated CLL cutaneous location is very rare and may be diagnosed late, as in the case of our patient. A better knowledge of the course of the illness and rapid diagnosis of this CLL cutis leukemia will enhance the therapeutic efficacy of the disease.

Abstract Background In the literature, reported cases of Acquired hemophilia A (AHA) induced by COVID-19 vaccination occurred after Adenoviral Vector Deoxyribonucleic Acid (DNA)- and SARS-CoV-2 Messenger Ribonucleic acid (mRNA)-Based vaccines. Here, and to the best of our knowledge, we report the first case of AHA occurring after an inactivated Sinovac-coronavac COVID-19 vaccine. Case presentation A 69-year-old Tunisian male patient consulted for severe left leg pain limiting physical mobility due to a 5*6 cm large ecchymosis located at the left inner thigh, having spontaneously appeared 5 days prior consultation and without notion of trauma. The patient had no known personal medical history. He had received the second dose of CoronaVac-SinoVac vaccine 30 days prior to consultation. Further physical examination revealed the presence of two other ecchymoses: one at the inner face of the right forearm, starting at the wrist reaching the elbow and the other at the left flank of the abdomen. Diagnosis of AHA was based on clinical presentation and confirmed with prolonged a PTT, Factor VIII deficiency and the presence of an FVIII inhibitor. The patient was successfully treated with corticosteroids and low dose Rituximab. Conclusion Clinicians should consider AHA in front of prolonged aPTT with or without spontaneous bleedings even after inactivated virus COVID-19.
