In some tumors, particularly those with a nodular pattern
, cells with appreciable pale cytoplasm and tinctorial properties reminiscent of the cells in many thecomas are seen.
(19) Furthermore, the most commonly observed pattern in the study was the nodular pattern
, which constituted 48.1%.
; At MG, there is nodular subareolar density.
An inguinal lymph node biopsy revealed predominant diffuse to nodular pattern
of small monotonous lymphocytes, suggestive of B cell lymphoma.
Bone marrow trephine biopsy was available in 84 cases; 3 types of growth patterns were noted: interstitial, nodular and packed with nodular pattern
constituting maximum number of cases (Table 2] (Figure 2].
(11,12) The nodular pattern
of growth, presence of collagenous stroma between the nodules, and presence of three distinct types of vessels according to immunostaining can differentiate it from other splenic vascular tumors.
Sections from the ileal lesion showed expansion of the submucosa by a lymphohistiocytic infiltrate with a vaguely nodular pattern
Retrospective studies indicate that the coarse nodular pattern
is a risk factor for the development of HCC [11-15].
The patterns of peritoneal involvement were identified as smudged pattern (increased density or soft tissue permeation of the omental fat), nodular pattern
(enhancing soft tissue nodules), omental caking (diffusely thickened masses replacing normal omental fat), cystic pattern (soft tissue masses with cystic component) and mixed pattern (having two or more of above described patterns).
It has various morphological patterns--nodular, vesicular, pustular, bullous and necrotic--with the nodular pattern
being the most common.
The four major histopathologic patterns of CMV lung infection are the (1) miliary or nodular pattern
with an exuberant intra-alveolar fibrinopurulent exudate, (2) the diffuse interstitial form with features of diffuse alveolar damage and interstitial edema, (3) a hemorrhagic form with diffuse recent hemorrhage, and finally (4) the bland, noninflammatory pattern with minimal evidence of lung pathology.
The various patterns that we could retrospectively identify on ultrasound were the nodular pattern
(57.14%), followed by the diffuse (28.5%) and the sclerosing pattern (14.3%).
