Histiocytes of Adrenalctomized Mice

Mucoprotein-containing histiocytes (muciphages) in the rectum.

Mucoprotein-containing macrophages (muciphages) are a common finding in routine rectal biopsies, occurring in about 50% of cases. No correlation was found between their presence and the sex, age, and disease of the patient. They must be distinguished from the cells of Whipple's disease and from lipofuscin-containing macrophages. The origin of the mucoprotein is discussed and rectal epithelial m...

Hansen's fingerprints in bone marrow histiocytes

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 47-year-old man from a region endemic for leprosy presented with a 1-month history of high grade fever and red, raised skin lesions on the upper limbs. He had multiple tender papules and nodules on his forearm and thigh along with sensory loss and thickeni...

Pigmented epithelioid melanocytoma: immunohistochemical profiles of tumour-infiltrating histiocytes.

Sea-blue-colored histiocytes associated with bone marrow granulomas.

A 77-year-old man was admitted for evaluation of pancytopenia. His blood examination revealed hemoglobin 9.7 g/dL, platelet count 149 3 10/L, and white blood cell count 3.2 3 10/L with normal differential. Peripheral blood smear showed red blood cells with anisocytosis, microcytes, and teardrop-shaped cells. There was mild leukopenia with relative monocytosis and normal platelets. Bone marrow b...

Thyroglobulin immunoreactivity in lymph node histiocytes: a potential diagnostic pitfall.

AIMS Strong thyroglobulin immunoreactivity within sinus histiocytes in a lymph node draining a papillary thyroid carcinoma was observed in a recent case. This prompted the investigation of whether thyroglobulin immunoreactivity is common in regional lymph nodes in cases of thyroid malignancy. METHODS Eighty seven lymph nodes were studied from 21 cases of thyroid malignancy. These comprised pa...
