Whipple's disease Whipple's disease Whipple's disease is a rare, systemic infectious disease caused by the bacterium "Tropheryma whipplei". First described by George Hoyt Whipple in 1907 and commonly considered a gastrointestinal disorder, Whipple's disease primarily causes malabsorption but may affect any part of the body including the heart, brain, joints, skin, lungs and the eyes. Weight loss, diarrhea, joint pain, and arthritis are common presenting symptoms, but the presentation can be highly variable and approximately 15% of patients do not have these classic signs and symptoms. Whipple's disease is significantly more common in men, with 87% of the patients being male. When
Extramammary Paget's disease in 1893, Darier and Coulillaud described the perianal location of EMPD. Extramammary Paget's disease Extramammary Paget’s Disease (EMPD), is a rare and slow-growing malignancy which occurs within the epithelium and accounts for 6.5% of all Paget’s disease. The clinical presentation of this disease is similar to the characteristics of Mammary Paget’s disease (MPD). However, unlike MPD, which occurs in large lactiferous ducts and then extends into the epidermis, EMPD originates in glandular regions rich in apocrine secretions outside the mammary glands. EMPD incidence is increasing by 3.2% every year, affecting hormonally-targeted tissues such as the vulva and scrotum. In women,
