kansasii), reactive hyperplasia, cat scratch disease, fungal infection, toxoplasma lymphadenitis, sarcoidosis, berylliosis
, bacterial adenitis, and Kikuchi disease (idiopathic histiocytic necrotizing lymphadenitis).
The light microscopic findings seen in HP are by no means specific, having overlapping features with numerous diseases, including (but not limited to) sarcoidosis (particularly early sarcoidosis), berylliosis
, lymphoid interstitial pneumonia (LIP), and low-grade lymphoma (particularly extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue lymphoma), drug reactions, infections, aspiration, and conditions that have a UIP pattern and nonspecific interstitial pneumonia pattern.
(2) Environmental exposures such as berylliosis
or pneumoconiosis may also be considered in the differential in certain clinical situations.

Causes are varied and include tuberculosis; other mycobacteria or fungi infections; vasculitis, for example, Wegener's granulomatosis and Churg-Strauss syndrome; chronic berylliosis
or another metal exposure disease; foreign body reactions; and lymphoma .

and pulmonary sarcoidosis mimic one another on imaging and pathology and have more of a tendency for interstitial thickening.
: summary and survey of all clinical types observed in a twelve-year period.
Other granulomatous diseases, such as berylliosis
and tuberculosis, must be excluded since they often present the same way as scar sarcoidosis.
(10) In their efforts to prevent OSHA and EPA from promulgating protective regulations limiting human exposure to beryllium, they took every opportunity to "manufacture uncertainty" about the science documenting the fact that exposure to beryllium caused lung cancer and a debilitating and usually fatal disease called chronic beryllium disease (CBD), or berylliosis
. (11) The primary vehicle that Brush Wellman employed for this purpose was a blue ribbon panel called the Beryllium Industry Scientific Advisory Committee (BISAC).
Asbestosis and berylliosis
([dagger]) also were diagnosed.
