286. Explanation
A) • The fungal hyphae are broken down into smaller
sections/compartment by septa → septate hyphae
Example: Apergillus
• If there is no septation/compartment → Non-septate
(Coenocytic)
Mucor, Zygomycetes

285. Explanation
A) • Meningococcal disease is associated with terminal
complement deficiency (C5-C9) which forms the membrane attack complex. Hence the bactericidal activity is reduced in this condition and increases susceptibility to invasive meningococcal infection up to 600 times

284. Explanation
A) • Epithelioid cells are defined as cells that resemble
epithelial cells (keratinocytes). They have large oval, pale,
vesicular nuclei and abundant eosinophilic cytoplasm.
• The best-known epithelioid cells are those derived from
macrophages within granulomas, but tumor cells can
also be described as epithelioid. Immunostaining may be
needed to identify the type of epithelioid cell.
MOST COMMON LESIONS WITH EPITHELIOID CELLS
• Granulomas
• Squamous cell carcinoma
• Spitz nevus (spindle and epithelioid cell nevus)
• Melanoma
