Clinical, Dermatoscopic, and Histological Findings in a Diagnosis of Pityriasis Lichenoides

A Rare Case of Papular-Purpuric "Gloves and Socks" Syndrome Associated with Influenza

Papular‐purpuric “gloves and socks” syndrome (PPGSS) is a unique, self‐limited dermatosis characterized by edema, erythema, and pruritic petechiae and papules in a distinct “gloves and socks” distribution. This is often accompanied by systemic symptoms, including fever, lymphadenopathy, asthenia, myalgia, and arthralgias. PPGSS has also been described as a manifestation of an underlying immunological mechanism that can be triggered by viral or drug‐related antigens. A 32‐year‐old male developed a painful eruption on the bilateral hands and feet after being diagnosed with influenza B. On examination, scattered papular purpura with occasional overlying scale was noted on the bilateral hands, fingers, feet, toes, volar wrists, and ankles. Histopathologic sections showed a mixed pattern of inflammation with interface and spongiotic changes. A parakeratotic scale with overlying basket‐weave orthokeratosis was also seen. Within the epidermis, there was intraepidermal vesicles and Langerhans cell microabscess formation with scattered apoptotic keratinocytes. The underlying dermis showed a superficial perivascular lymphocytic infiltrate with mild edematous changes, and extravasation of red blood cells. Clinicopathologic correlation strongly supported a diagnosis of popular‐purpuric gloves and socks syndrome. The influenza virus has never been reported in association with PPGSS; thus, this case outlines an important new variant that clinicians should be familiar with.

Phototherapy in dermatological maladies (Review)

Since the introduction of modern phototherapy in 1903 by Nobel Prize-winner Niels Ryberg Finsen, the usage of this therapy in the medical field has grown, techniques have been refined and developed, and it has gained widespread acceptance. Psoriasis vulgaris, parapsoriasis, lichen planus, atopic dermatitis, neonatal jaundice, urticaria, morphea, vitiligo, granuloma annulare and cutaneous T cell lymphoma are only a few dermatological indications that come along with satisfactory results. Most often, it is a 2nd or 3rd line therapy being an alternative in more severe or refractory diseases. Despite the side effects that may occur after phototherapy, which are often minor, the benefits can be significant. Unfortunately, the absolute contraindications limit the use of this type of treatment and implicitly the management of these patients. The current review aimed to combine the recommendations of phototherapy in dermatology, the types of phototherapy that can be suitable for certain dermatological diseases and to emphasize its importance in certain conditions that are associated with significant remission rates.
