Lepromatous phlebitis of the external jugular vein.

Mycobacterium leprae (M leprae), the causative agent of Hansen's disease, is endemic in many areas of Asia, sub-Saharan Africa, South and Central America, the Pacific Islands, and the Philippines. The spectrum of clinical disease is dependent on the patient's cell-mediated immunity and might range from localized anesthetic patches or plaques to disseminated disease. If undiagnosed, progression with damage to the involved sensory and motor nerves might occur.

Histologic features of surgically removed fallopian tubes.

Context: The fallopian tube is a common specimen in a pathology laboratory. It may be examined either alone as a salpingectomy or tubal ligation specimen, or as part of a more complex specimen from a hysterectomy and/or oophorectomy operation. Although the common histologic findings in the fallopian tube have been described previously, to our knowledge no study has documented the frequency of histologic changes in fallopian tubes removed for all reasons or associations with clinical history.
