Lymphomatoid papulosis (LyP) is a chronic skin condition, characterized by recurrent eruptions of papules and nodules with or without central necrosis that spontaneously resolve. This condition was originally described by Macaulay in 1968 as a self-healing rhythmical paradoxical eruption that was clinically benign yet histologically malignant.1 Clinically, it is defined by papules that wax and wane, are generally less than 1cm in diameter, and heal spontaneously after 6–8 weeks with subsequent scarring.2

Developing highly-efficient electrocatalysts for the nitrate reduction reaction (NITRR) is a persistent challenge. Here, we present the successful synthesis of 14 amorphous/low crystallinity metal nanofilms on three-dimensional carbon fibers (M-NFs/CP), including Al, Ti, Mn, Fe, Co, Ni, Cu, Zn, Ag, In, Sn, Pb, Au, or Bi, using rapid thermal evaporation. Among these samples, our study identifies the amorphous Co nanofilm with fine agglomerated Co clusters as the optimal electrocatalyst for NITRR in a neutral medium.

Halo nevus is a benign type of melanocytic nevi commonly found in children and manifests as a central pigmented part surrounded by a well-defined hypopigmented area. Halo nevi are commonly located on the trunk. The central nevus may show partial or complete regression, whereas the associated halo may persist or enlarge.

Lymphomatoid papulosis (LYP), the most common primary cutaneous CD30-positive lymphoproliferative disorder, is heralded by multiple papular and nodular lesions at anatomically discontiguous cutaneous sites. The histologic patterns are protean. An uncommon form of LYP is one that is anatomically confined.

A 59-year-old woman presented with a persistent eruption manifested as multiple agminated miliary facial papules. Histopathological examination showed prominent nodular dermal lymphoid infiltrates with hyperplastic follicles that were initially interpreted as B-cell reactive lymphoid hyperplasia. Several years later, an additional biopsy showed a dense perifollicular infiltrate with reactive primary and secondary follicles.
