| Code | Diagnosis | Comment | Score |
| anonymous | Opportunistic infection, differential diagnoses include toxoplasmosis, histoplasmosis and leishmaniasis. (100%) | Grocott and Giemsa stains for further assessment, correlate with culture result. | 100 |
| anonymous | Pneumocystic carinii | nil | 80 |
| anonymous | Necrotising inflamation and acute lung injury | Special stains with Grocott, PAS, mucicarmine, Warthin-Starry and Dieterle to exclude different fungal organisms, Legionella pneumonia, Rhodococcus Equi, cryptococcus and Pneumocystis jiroveci. Immunostains with CMV and herpes. | 80 |
| anonymous | Necrosis, favor toxoplasmosis (70%); Ddx Histoplasma (10%), Mycobacteria (10%), Fungus (10%). | Immunohistochemical studies for toxoplasma. Special stains for mycobacteria (acid-fast), fungus (grocott). | 100 |
| anonymous | NECROTIZING LESIONS SUGGESTIVE OF TOXOPLASMOSIS. | CONFIRM BY IMMUNOSTAIN. ALSO IMMUNOSTAINS AND GROCOTT STAIN TO EXCLUDE OTHER OPPURTUNISTIC INFECTION EG. ADENOVIRUS, CMV, ASPERGILLOSIS, PCP etc. | 100 |
| anonymous | Necrotic nodules, favor infective causes, e.g. pneumocystitis, toxoplasma, etc. 100% | Do infective stains, e.g. Grocott, Ziehl Neelsen, Gram, mucicarmine stains; also pneumocystis immunostain. | 100 |
| anonymous | Necrotizing pneumonia 100% | Pending special stains for identification of causative organisms: Toxoplasma (70%), Pneumocystis (20%), cryptococcus (9%), adenovirus (1%) | 100 |
| anonymous | Infective microorganism present, suggestive of toxoplasmosis | To perform Ziehl Neelsen, Gram and Warthin Starry to rule out other infectious causes | 100 |
| anonymous | necrotizing pneumonia, rule out infective agents: toxoplasmosis, cytomegalovirus | nil | 100 |
| anonymous | Presence of multifocal miliary small nodular area with sign of necrosis of alveolar wall surrounded by reactive pneumocytes, suggestive of viral infection in immunosuppressive patient. Also seen in superimposed with other infection. | nil | 80 |
| anonymous | Necrotizing inflammation | Infection especially opportunistic ones such as fungal infection due to Pneumocystis carinii and viral infection need to be excluded. Ancillary studies including special stains (Grocott, PAS and Ziehl Neelsen stains) and immunohistochemical studies for viral inclusion (such as CMV) are suggested. Correlation with microbiological and viral culture is also mandatory. | 80 |
| anonymous | Multiple pulmonary necrosis and infarct | Consistent with infection; need to consider toxoplasmosis | 100 |
| anonymous | Necrotising pneumonia and diffuse alveolar damage, to exclude infective organisms such as toxoplasmosis (100%). | Immunostaining for toxoplasma, and special stains to rule out acid fast bacilli, fungi and pneumocystis will be useful. | 100 |
| anonymous | 265 necrotizing pneumonia, perform ZN, PASD, grocott to exclude TB, Nocardia, PCP and fungal infection (100% Probability) | nil | 80 |
| anonymous | Pneumocystis carinii pnenmonia 100% | Perform special stains to confirm the diagnosis, and to rule out other bacterial and fungal infections. | 80 |
| anonymous | Necrotizing pneumonia | Need to perform panel of infective stains (e.g. gram; fungal, ZN), especially look for nocardia, legionella infection. | 80 |
