Lupus and leg ulcers—a diagnostic quandary

Leg ulcerations can occur in systemic lupus erythematosus (SLE) patients with antiphospholipid (aPL) antibodies and/or vasculitis, and it has been suggested that aPL antibodies may play a pathogenetic role in skin manifestations of SLE. To our knowledge, there is only one report of an aPL antibody-negative patient who developed pyoderma gangrenosum (PG) several years before the diagnosis of SLE. We describe a case of a young male affected by SLE who developed leg ulcers diagnosed as PG in the absence of aPL antibodies, where the onset of PG was associated with reactivation of SLE. Effective treatment led to significant improvement in skin lesions and SLE activity.

A still image of a transient rash captured by a mobile phone

The diagnosis of adult onset Still’s disease (AOSD) can be difficult as the differential diagnosis is broad, it is based on clinical criteria and the signs, for example rash, can be transient. Clinical photography has an obvious role, and with modern technology, is now in the hands of physicians. We report a case of AOSD where an image of a transient rash taken with a camera phone allowed the diagnosis to be established. Further, we discuss the controversies around hospital bans on mobile phones (due to potential incompatibility with medical devices) and the reality of their widespread use. We conclude that, providing safeguards of consent and data storage are in place, the camera phone is a useful tool in rheumatology practice.

Losing all sense: a case of meningeal carcinomatosis

Meningeal carcinomatosis (MC) is diffuse infiltration of the meninges by metastatic carcinoma. Though a known complication of solid tumours, it is rarely seen as a presenting feature of such cancers. Here, the authors describe the case of a 64-year-old lady who presented with rapid-onset hearing loss and progressive visual loss, among other cranial nerve palsies. A primary non-small cell lung cancer was later identified by CT, but the diagnosis of MC was only confirmed after cytological analysis of a repeat lumbar puncture. Immunophenotyping of cells from the lung biopsy correlated with cells obtained from cerebrospinal fluid. In view of her rapid clinical deterioration, chemotherapy was not pursued, and the patient was transferred to a hospice 3 weeks after admission.

Metastatic renal cell carcinoma presenting with mediastinal eggshell calcification.

An 81-year-old South Asian man normally resident in the UK presented with night sweats for over 2 months on a background of weight loss of 4 kg in 6 months. His medical history was significant for metastatic renal cell carcinoma treated 5 years previously with cytoreductive nephrectomy and adjuvant chemotherapy. Following an abnormal chest radiograph showing an ill-defined right paratracheal mass, a CT scan showed eggshell calcification (circumferential calcification) of enlarged low right paratracheal lymph nodes. An endobronchial ultrasound–guided transbronchial needle aspiration of an involved large paratracheal lymph node showed cytology consistent with metastatic renal cell carcinoma.
