Pityriasis rubra pilaris (PRP; MIM 173200) is an uncommon papulosquamous inflammatory dermatosis. Only a few cases of PRP associated with an underlying malignancy have been documented. We investigated a 59-year-old patient presenting with a fulminant form of PRP recalcitrant to systemic retinoid therapy, in whom the skin disease heralded a diagnosis of cholangiocarcinoma. We searched the MEDLINE database to find articles reporting on similar associations of PRP with malignancies. We identified 10 studies linking PRP and malignancies, but an association between PRP and cholangiocarcinoma has not yet been reported...

The follicular presentation of psoriasis is a well-described but uncommon variant. In some cases, follicular psoriasis may clinically and histopathologically mimic pityriasis rubra pilaris. There are several reports discussing the resemblance of widespread follicular psoriasis in children to pityriasis rubra pilaris. We describe a case of follicular psoriasis in a 16-year-old black girl with acrally distributed follicular hyperkeratotic papules with associated keratoderma of her plantar surfaces resembling pityriasis rubra pilaris...

Pityriasis rubra pilaris (PRP) is a chronic disorder of keratinization of unclear pathogenesis. PRP-like eruptions induced by drugs have rarely been described. A previously healthy 29-year-old man presented with a generalized, rapidly spreading, erythematosquamous dermatosis, that started three days after initiation of subcutaneous insulin therapy for diabetes mellitus type 1. Clinical and histopathological features were consistent with a PRP-like eruption, possibly due to insulin therapy. The patient was switched to insulin analogue therapy and a complete healing of all lesions was achieved after two months...

Importance: We found CARD14 mutations (2 de novo novel mutations and another previously reported mutation) in 3 of 3 patients with pityriasis rubra pilaris (PRP) type V, but not in patients with PRP of other types. Our findings, combined with the published literature, suggest that type V PRP, both familial and sporadic, can be caused by CARD14 mutations. Detailed clinical observation revealed that all 3 patients displayed unique patchy macular brown hyperpigmentation. Objective: To further determine how often patients with PRP have pathogenic mutations in CARD14 and to elucidate which clinical subtype of PRP is caused by CARD14 mutations...

REVIEW
Enzo Errichetti, Giuseppe Stinco
Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), papulosquamous/papulokeratotic dermatoses (lichen planus, pityriasis rosea, papulosquamous sarcoidosis, guttate psoriasis, pityriasis lichenoides chronica, classical pityriasis rubra pilaris, porokeratosis, lymphomatoid papulosis, papulosquamous chronic GVHD, parakeratosis variegata, Grover disease, Darier disease and BRAF-inhibitor-induced acantholytic dyskeratosis), facial inflammatory skin diseases (rosacea, seborrheic dermatitis, discoid lupus erythematosus, sarcoidosis, cutaneous leishmaniasis, lupus vulgaris, granuloma faciale and demodicidosis), acquired keratodermas (chronic hand eczema, palmar psoriasis, keratoderma due to mycosis fungoides, keratoderma resulting from pityriasis rubra pilaris, tinea manuum, palmar lichen planus and aquagenic palmar keratoderma), sclero-atrophic dermatoses (necrobiosis lipoidica, morphea and cutaneous lichen sclerosus), hypopigmented macular diseases (extragenital guttate lichen sclerosus, achromic pityriasis versicolor, guttate vitiligo, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and postinflammatory hypopigmentations), hyperpigmented maculopapular diseases (pityriasis versicolor, lichen planus pigmentosus, Gougerot-Carteaud syndrome, Dowling-Degos disease, erythema ab igne, macular amyloidosis, lichen amyloidosus, friction melanosis, terra firma-forme dermatosis, urticaria pigmentosa and telangiectasia macularis eruptiva perstans), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), erythrodermas (due to psoriasis, atopic dermatitis, mycosis fungoides, pityriasis rubra pilaris and scabies), noninfectious balanitis (Zoon's plasma cell balanitis, psoriatic balanitis, seborrheic dermatitis and non-specific balanitis) and erythroplasia of Queyrat, inflammatory cicatricial alopecias (scalp discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia and folliculitis decalvans), nonscarring alopecias (alopecia areata, trichotillomania, androgenetic alopecia and telogen effluvium) and scaling disorders of the scalp (tinea capitis, scalp psoriasis, seborrheic dermatitis and pityriasis amiantacea)...

INTRODUCTION: Papulosquamous diseases are characterized by scaly papules and plaques with similar clinical picture which amounts to confusion and hence, a definitive histopathological diagnosis goes a long way in treatment of such diseases. AIM: The aim of the study was to study the histomorphology of non-infectious, erythaematous, papulosquamous lesions of skin with clinicopathological correlation. MATERIALS AND METHODS: Skin biopsies from 150 clinically diagnosed/suspected non-infectious erythaematous, papulosquamous skin diseases were received in the Department of Pathology...

Pityriasis rubra pilaris is a rare inflammatory disorder characterized by follicular papules on an erythematous base often exhibiting islands of unaffected skin, follicular plugging, and palmoplantar hyperkeratosis. While vitamin A deficiency and autoimmune reactions have been hypothesized as possible etiologies of this condition, pityriasis rubra pilaris-like eruptions secondary to medications are extremely rare. To our knowledge, only three other cases have been reported, and pityriasis rubra pilaris has never been reported in association with bevacizumab...

Pityriasis rubra pilaris is a rare heterogeneous disorder characterized by follicular keratosis, perifollicular erythema and palmoplantar hyperkeratosis. The aetiology is still unknown. In the majority of cases some triggering factors are found such as trauma or bacterial infection, possibly on a predisposed condition. In other cases, some immunological disorders are associated, and in familial cases a genetic disorder of keratinization has been suggested. The evolution is variable according to the clinical type...

Last years, the development of biological drugs substantially improved the outcome of many inflammatory diseases. In dermatology, this kind of therapy is essentially prescribed for the treatment of psoriasis, and include the anti-TNF, anti-IL-12/IL-23 and anti-IL-17. Despite these treatments have not yet been approved, they seemed to be efficient for the treatment of many other inflammatory dermatosis, like granulomatous diseases, neutrophilic diseases, hydradenitis suppurativa or pityriasis rubra pilaris.

Wong-type dermatomyositis (DM) is a rare variant characterized by keratotic follicular papules that may mimic pityriasis rubra pilaris. Histopathologic examination shows follicular and non-follicular epidermal invaginations filled with keratin. The diagnosis is often delayed. Twenty-four cases of Wong-type DM have been reported thus far in the literature. Herein, we report the clinical and histopathologic findings of three additional cases in order to raise awareness of the disorder.

Pityriasis rubra pilaris is a chronic inflammatory dermatosis of unknown etiology and great clinical variability. It has been divided into six categories. Types III, IV, and V occur in childhood and are distinguished by their clinical presentation, age of onset, and course. We report a 19-year-old male patient with a 2-week history of pruritic, scaling dermatosis of the hands, feet, elbows, and knees. He had no family history of skin disease. On physical examination, we observed circumscribed, reddish-orange, scaling plaques affecting the elbows and knees and a waxy palmoplantar keratoderma...

BACKGROUND: Clinicians have recognized the impact of cutaneous signs and symptoms in patient's quality of life over the years. Often, systemic response to a certain therapy is faster than the cutaneous response, leading to patient frustration and treatment discontinuation. Brimonidine gel is an alpha-2 adrenergic agonist recently approved by the FDA for the treatment of persistent facial erythema of rosacea. OBJECTIVES AND METHODS: We describe 3 patients with recalcitrant facial erythema secondary to dermatomyositis, pityriasis rubra pilaris and systemic lupus...

IMPORTANCE: Pityriasis rubra pilaris (PRP) is a rare papulosquamous disorder with limited epidemiologic and clinicopathologic data. Little information is available on long-term outcomes, comorbidities, and treatment efficacy. OBJECTIVE: To evaluate objective and subjective disease experience metrics from the perspectives of patients and clinicians. DESIGN, SETTING, AND PARTICIPANTS: One hundred patients with a putative diagnosis of PRP and who elected to participate completed a comprehensive survey, followed by acquisition of their medical records, including histopathology slides and reports...
