  Desmoid tumors of the pleura
  Desmoid tumors of the pleura are also in the differential diagnosis of desmoplastic mesothelioma. In this lesion, the proliferating cells are myofibroblasts rather than mesothelial cells, and the proliferating cells are distinguished by their morphology and by their expression of smooth muscle actin.

• pleural scar

  A pleural scar can show extension into subpleural fat and skeletal muscle. A lymphoid follicle can be seen in the pleural scar.

• pleural desmoplastic mesothelioma
  5 January 2015

  A subset of sarcomatoid mesotheliomas, desmoplastic mesothelioma, typically produces a dense and bland collagenous matrix that can be exceedingly difficult to distinguish from active pleural fibroplasias.
  Synopsis
  desmoplasia
  bland basket-weave fibrosis.
  The entrapped spindle cells show plump nuclei and prominent nucleoli.
  Possible invasion of the soft tissues of the chest wall.
  Differential diagnosis
  Desmoplastic sarcomatoid mesothelial growth may represent the primary or (...)

• pleural atypical mesothelial hyperplasia
  5 January 2015

  DIfferential diagnosis
  An indeterminate biopsy showing severely atypical mesothelial hyperplasia, in the background of occupational exposure to asbestos, clinical, radiographic, or gross findings compatible with MM, should prompt the surgical pathologist to phrase the final diagnosis as “atypical mesothelial hyperplasia without diagnostic features of malignancy, however, mesothelioma cannot be excluded with confidence.” This leads the clinician to consider what, if any, diagnostic tests must (...)

• asbestos-associated fibrinous pleural effusion
  5 January 2015

  asbestos-related fibrinous pleural effusion
  A history of occupational exposure to asbestos broadens the differential diagnosis to include localized benign hyaline plaques, diffuse pleural fibrosis, and asbestos-associated fibrinous pleural effusions. All of these processes can at times mimic mesothelioma.

• diffuse pleural fibrosis
  5 January 2015

  A history of occupational exposure to asbestos broadens the differential diagnosis to include localized benign hyaline plaques, diffuse pleural fibrosis, and asbestos-associated fibrinous pleural effusions. All of these processes can at times mimic mesothelioma.

• serous non-inflammatory effusion
  5 January 2015

  serous non-inflammatory effusions
  Differential diagnosis
  Disorders that are generally caused by serous non-inflammatory effusions, including long-standing congestive heart failure, cirrhosis, kidney, and hypothyroidism can also cause difficulties in differential diagnosis with serous neoplasia.

• fibrinous pleuritis

  fibrinous pleural inflammation
  Types
  acute fibrinous pleuritis
  organizing fibrinous pleuritis
  Synopsis
  presence of fibrin
  mesothelial hyperplasia
  increased numbers of eosinophils
  dystrophic calcifications
