In PT, areas with marked overgrowth and stromal cellularity
with leaflike stromal fronds may be present only as minor foci within a seemingly fibroadenoma.
In some cases, the ThinPrep slide has insufficient cellularity
for ALK FISH testing.

in patients: a meta-analysis.
Visceral organ mass and cellularity
in growth-restricted and refed beef steers.
Caption: Figure 4: Presurgical images of a 52-year old GBM patient show a ring-enhancing mass with central necrosis on the T1 postcontrast image (a), disrupted blood brain barrier on leakage [[lambda].sup.tr] (b) and vessel density on [V.sub.p] (c) maps overlaid on the T1-weighted image, and cellularity
on the diffusion-weighted image (DWI) (d).
However, part of the primary lesion showed conspicuous nucleoli and high cellularity
, consistent with atypical carcinoid according to the former criteria .
Fibroblastic cells are spindled to stellate with variable cellularity
set in a collagenous stroma.
The pathology result was high grade malign mesenchymal tumor with high cellularity
, extensive necrosis, mitosis 40/10 BBA, and moderate atypia.
In addition, histologic features, such as cellularity
and mitosis, may be misinterpreted as a malignancy.
Two months after uncomplicated normal vaginal delivery, the patient presented to the hospital with aplastic anemia, evident by her complete blood count: WBC of 1 x [10.sup.9]/L, absolute neutrophil count (ANC) of 0.05, Hb of 7.8g/dL, and Plt of 5 x [10.sup.9], and the bone marrow biopsy revealed markedly reduced cellularity
with many lymphoid aggregates and no clear dysplastic changes or evidence of malignancy.
The major prognostic features were cellularity
, mitotic rate, and nuclear grade in a 3 step classification by Folpe and Weiss (4) grouping OFMT in a) typical form with low cellularity
, mitotic rate <2/50 HPF, and low nuclear grade; b) malignant form with high cellularity
and nuclear grade, mitotic rate >2/50 HPF; and c) atypical with intermediate grade between a and b.
All these cases had low cellularity
leading to nondiagnostic material or an erroneous benign diagnosis.
