    There is presently no line of distinction between oral lichen planus and other oral lichenoid lesions. The aim of this study is to determine using histomorphometry, the differences between these lesions. Paraffin sections from 7 normal buccal epithelium, 19 oral lichen planus (LP), 14 oral lichenoid lesions (LL) and 7 discoid lupus erythematosus-like lesions (DLE-ll) were selected. The nuclear volume (V(N)) and cellular-volume (V(CELL)) of the epithelium were assessed using an image analyser. The V(N) and V(CELL), derived for both basal and spinal strata in LP and DLE-ll were 2.3 times more than that of normal tissues. There was a significant difference between LP and LL (P < 0.005) and between LL and DLE-ll (P < 0.001), but not between LP and DLE-ll. In conclusion, there appears to be a difference between LP, LL and DLE-ll and V(N) and V(CELL) may serve as potential discriminators between these groups of lesions.

    BACKGROUND: The most common autosomal form of Chronic Granulomatous Disease, p47-phox deficient CGD, generally features a GT (deltaGT) deletion in the GTGT sequence at the start of exon 2 on the NCF-1 gene. This consistency is due to the coexistence of and the recombination between 2 homologous pseudogenes (psi s) and NCF-1. The GTGT: deltaGT ratio mirrors the NCF-I: NCF-1 psi ratio and is 2:4 in normal individuals.
    OBJECTIVE: To determine the molecular basis of the Autosomal-CGD in a family with 2 children, a male and female, affected by the disease. The female patient suffered recurrent infection, retinitis pigmentosa and discoid lupus.
    METHODS: Chemiluminescence (CL) was used to study the respiratory burst, while genetic analysis was done by RT-PCR, PCR, deltaGT and the 20bp gene scans.
    RESULTS: The CL response of the patient was profoundly low. The patient's p47-phox band was absent in the RT-PCR for NADPH-oxidase component mRNAs. The deltaGT scan showed that the patient's GTGT: deltaGT ratio was 0:6, the parents' and the younger brother's was 1:5 and the younger sister's was 2:4. Examination of other NCF-1/ NCF-1 psi s differences showed that the father had a compound deltaGT allele ie. deltaGT-20bp, inherited by the patient, and that both parents had compound GTGT alleles with a single 30bp segment in intron 1.
    CONCLUSIONS: The patient was a classic, homozygous deltaGT p47-phox deficient CGD with one allele harbouring a compound deltaGT-20bp gene. The deltaGT and 20bp gene scans offer a relatively simple and efficient means of defining a p47-phox deficient CGD patient.
