Background and aims: Small fiber neuropathy (SFN) is increasingly suspected in patients with pain of uncertain origin, and making the diagnosis remains a challenge lacking a diagnostic gold standard. Methods: In this case–control study, we prospectively recruited 86 patients with a medical history and clinical phenotype suggestive of SFN. Patients underwent neurological examination, quantitative sensory testing (QST), and distal and proximal skin punch biopsy, and were tested for pain-associated gene loci. Fifty-five of these patients additionally underwent pain-related evoked potentials (PREP), corneal confocal microscopy (CCM), and a quantitative sudomotor axon reflex test (QSART). Results: Abnormal distal intraepidermal nerve fiber density (IENFD) (60/86, 70%) and neurological examination (53/86, 62%) most frequently reflected small fiber disease. Adding CCM and/or PREP further increased the number of patients with small fiber impairment to 47/55 (85%). Genetic testing revealed potentially pathogenic gene variants in 14/86 (16%) index patients. QST, QSART, and proximal IENFD were of lower impact. Conclusion: We propose to diagnose SFN primarily based on the results of neurological examination and distal IENFD, with more detailed phenotyping in specialized centers.

Mammary Paget’S Disease

Mammary Paget’s disease accounts for 1% to 3% of all breast tumors and manifests as a chronic eczematous lesion of the areolar skin. It can occur without any underlying neoplasia or can be present in association with an underlying invasive and/or in situ carcinoma of the breast. The present report describes a challenging nipple punch biopsy showing an infiltration of the lower third to two-thirds of the epidermis by large, ovoid, neoplastic cells. The morphology was consistent with mammary Paget's disease, although immunohistochemistry for cytokeratin-7 (CK7) was repeatedly negative. This resulted in an initial misdiagnosis and, subsequently, a delay in the patient's follow-up. Additional immunohistochemistry for GATA binding protein 3 (GATA3) and human epidermal growth factor receptor 2 (HER2), as well as a second opinion of a breast pathologist, resulted in the diagnosis of mammary Paget's disease. The aim of this article is to raise awareness among pathologists and prevent them from misdiagnosing CK7-negative Paget disease of the breast.

Abstract Background Squamous cell carcinoma (SCC) of the scrotum was the first malignancy known to be associated with exposure to an occupational carcinogen—in this case, soot trapped in the breeches of chimney sweeps. Better civil rules and regulations and the replacement of hearths with other forms of heating have rendered SCC of the scrotum a rarity. We report two cases of scrotal SCC with vastly differing clinical presentations and management. Case presentation Case 1 had T1 N0 M0 disease and presented with a small (< 2 cm), innocuous-looking, non-healing ulcer of eight years duration. A punch biopsy revealed a superficially invasive SCC confirmed on immunohistochemical profiling. A wide local excision of the lesion was subsequently performed. Follow-up at three years showed no signs of recurrence. Case 2 presented with T4 N1 M1 disease and rapidly progressing locally destructive mass. A punch biopsy of the scrotal lesion confirmed invasive moderately differentiated focally keratinising SCC. The metastatic evaluation confirmed the presence of metastatic, extensive para-aortic lymphadenopathy. He was managed with cisplatin-based chemoradiotherapy. Conclusion Early detection and management of patients with SCC of the scrotum are essential. If the diagnosis is delayed, treatment options become limited, and the prognosis is poor. Notwithstanding the rarity of this disease, multicentre trials are needed to provide more precise guidelines as to the optimal management of these patients.

Cortical mapping with electrical stimulation (ES) in neurosurgical patients typically involves the manually controlled delivery of suprathreshold electrical current to a discrete area of the brain. Limited numbers of trials and imprecise current delivery methods increase the variability of the behavioral response and make it difficult to collect quantitative mapping data, which is especially important in research studies of human cortical function. To overcome these limitations, the authors developed a method for computer-controlled delivery of defined electrical current to implanted intracranial electrodes. They demonstrate that stimulation can be time locked to a behavioral task to rapidly and systematically measure the detection threshold for ES in human visual cortex over many trials. Computer-controlled ES is well suited for the systematic and quantitative study of the function of virtually any region of cerebral cortex. It may be especially useful for studying human cortical regions that are not well characterized and for verifying the presence of stimulation-evoked percepts that are difficult to objectively confirm.
