Subcutaneous panniculitis-like T-cell lymphoma and lupus erythematosus profundus: a diagnostic dilemma.

A white Caucasian woman in her 30s presented with an indurated lesion on her right upper arm. Panniculitis was clinically suspected. Antinuclear antibody testing was positive but incisional biopsy showed subcutaneous panniculitis-like T-cell lymphoma (SPTCL), although with some unusual features more in keeping with lupus. Initial treatment was with oral prednisolone and radiotherapy but with only partial response. A second biopsy was taken from an area of presumed residual disease. This displayed histological features that were much more typical of lupus erythematosus profundus (LEP) but with tiny foci suggesting concomitant microscopic areas of SPTCL. Immunofluorescence for IgM was positive. This case highlights the rare occurrence of a patient with overlapping clinical and pathological features of SCPTL and LEP. It emphasises the need for close clinicopathological correlation in the workup of patients with suspected panniculitis and the importance of careful pathological examination for features of both diseases.

Posterior nasal neurectomy for intractable rhinitis: A systematic review of the literature.

BACKGROUND: Rhinitis affects up to 40% of the population worldwide and can significantly reduce quality of life. Some patients remain symptomatic despite maximal medical therapy. In refractory cases, posterior nasal neurectomy (PNN-the endoscopic division of the intranasal nerve branches containing postganglionic parasympathetic fibres) is postulated to reduce symptom burden. OBJECTIVES OF REVIEW: To establish whether PNN is effective and safe in the management of allergic and non-allergic rhinitis. TYPE OF REVIEW: Systematic review. METHODS: A comprehensive literature search was undertaken using PubMed, EMBASE, MEDLINE, and Cochrane. The inclusion criteria were: studies published in English, studies where PNN was performed either with or without additional procedures, and where measures of objective/subjective outcomes and/or complications were reported. Extracted data included study type, sample size, surgical technique, study population characteristics, follow-up period, outcome measures, complications of surgery, and symptom outcomes. RESULTS: A total of 23 articles satisfied the inclusion criteria studying in total 2282 patients. Sample size ranged from 8 to 1056. There were 3 randomised controlled trials, 3 case-control studies, and the remaining 17 were case series using both objective and subjective outcome measures. All but one study found improved patient-reported outcomes following PNN. Complications were reported in 14 studies-epistaxis was the most common complication and was observed in 30 patients (1.5% of subjects). CONCLUSIONS: PNN had a low rate of complications. Although most studies reported significant symptomatic improvement, their heterogeneity, level of evidence, study design, and/or quality was not sufficient to draw any firm conclusions on the effectiveness of the procedure. Larger, well-designed studies are needed to clarify its role in the management of difficult-to-treat rhinitis.
