Pictorial Presentation of Parasites by Herman Zaiman

Thanks to the generosity of Herman Zaiman and his family, ASTMH proudly presents “Pictorial Presentation of Parasites,” a famous collection of more than 2,000 slides of various vectors.

Dr. Zaiman, a longtime ASTMH member, spent his career as a radiologist and educator until retiring in 2000. He taught at Einstein College in New York. He also co-authored several medical texts, including "Photographic Case Studies in Gastroenterology: Diagnostic Tests for the Practitioner" in 1992. Additionally, his writing has appeared in journals such as the Journal of Histochemistry & Cytochemistry and the American Journal of Pathology.

His "Pictorial Presentation of Parasites" is a seminal image collection that will remain a valued resource for those in the tropical medicine and hygiene field for decades to come.

Egyptian male, approximately 10 years old. Urinary bladder with red elevated lesions at the apex and along the right ureteral orifice. Live eggs were not found distant to these foci suggesting that the adult worms nest at one site for some time. Eight pairs of adults were counted in the bladder vasculature.

Same patient had a stalked polyp of the sigmoid colon. The polyp contained numerous eggs of S. haematobium and a few eggs of S. mansoni. Isolated intestinal polyps are not infrequent amoung Egyptians infected with S. mansoni or S. haematobium. They are less frequently seen in Brazilians suffering from S. mansoni infections.

Egyptian male, 26 years old. Surgically excised urinary bladder, containing 156,000 eggs per gram of host tissue-. Eighteen pairs of adults wore recovered from the specimen. The pearly white area near the apex is indicative of squamous metaplasia. The largo ulcerated mass on the right side of the bladder is a squamous cell carcinoma. The tan surface of the remainder of the bladder is a mass of confluent sandy (granulomatous) patches.

Hemicolectomy specimen from 40 year old Egyptian male showing large bilharzioma adjacent to the rectosigmoid colon. Several polyps were present in the intestine. The bilharzioma was composed mainly of fibrotic granulomas, About 23, 000 S. mansoni eggs and 1, 500 S. haematobium eggs per gram of polyp and/or bilharzioma were present. Irregular fibrous masses were present in the colonic serosa as well. Numerous S. mansoni adults were found in the specimen. Surgery was scheduled to provide relief from urinary tract obstruction (right ureter) caused by S. haematobium. The colon was resected because the mass was suspected to be cancer.
