In addition, lymphocytes with abundant basophilic
cytoplasm containing small vacuoles are few but should be present in cases with leukemic involvement (9,10) (Figure 1, B).
Histopathologic examination of the nodular masses in the lungs revealed variably sized granulomas composed of large macrophages with abundant, grainy, basophilic
cytoplasm, which contained numerous acid-fast bacilli (Figs 6 and 7).
This theory dates back to 1969, when Schuknecht reported autopsy findings of basophilic
deposits on the cupula in subjects who had had a history of BPPV.
secretory cells contained extensive rough endoplasmic reticulum and numerous Golgi bodies; their ultrastructure did not differ among species (Fig.
Peripheral smear and bone marrow aspirate showed a predominant population (90%) of medium-sized cells with moderate amount of light basophilic
agranular cytoplasm with occasional cytoplasmic blebs, and slightly eccentric nucleus with relatively regular nuclear margins, less condensed chromatin and a single centrally placed nucleolus (Figure 1).
7% (1 L) in visceral mass Pathology of unknown etiology Basophilic
inclusions 14% (4 L, 3 M) 3.
In several birds within the macrophages, there were vacuoles that contained basophilic
small coccobacilli organisms that were about 0.
The intermediate cells frequently predominate; their appearance ranges from small basal cells with scanty basophilic
cytoplasm to larger and more oval cells with more abundant pale eosinophilic cytoplasm that appears to merge into epidermoid or mucous cells.
The stroma surrounding these tumor cells contained a basophilic
The oogonia had one large basophilic
nucleus and light basophilic
cytoplasm and developed into the previtellogenic oocytes (Fig.
The histologic diagnosis of pituitary adenomas classifies tumors as acidophilic, basophilic
, and chromophobic using conventional stains; acidophilic adenomas were said to be associated with acromegaly or gigantism, basophilic
adenomas were thought to be the cause of Cushing disease, and chromophobic tumors were considered to be nonfunctioning from the endocrine perspective.
The buffy-coat smear performed 4 days after illness onset showed basophilic
intracytoplasmic inclusions inside vacuoles of lymphocytes and monocytes, with typical features of morulae reported for human monocytic ehrlichiosis (Figure).
