Dear Editor, Pemphigus vegetans (PV) of Hallopeau is a rare and indolent variant of pemphigus clinically characterized by vegetating lesions preceded by pustules mainly in flexural areas (1,2). This helps us to differentiate it from PV of Neumann, which is a more extensive and refractory disease, more alike to a pemphigus vulgaris outbreak with blisters which turn into vegetating plaques (3). We report the clinical presentation, course, and therapeutic response in a patient diagnosed with PV of Hallopeau from its early stage during a 3-year follow up.

Dear Editor, Approximately 25-33% of cutaneous melanomas arise from nevi (1). Shitara et al. suggested that junctional and compound nevi are more likely give rise to melanoma than intradermal nevi, but this has not been definitively confirmed (2).

Article Synopsis
  • Segmental Darier disease (DD) is a rare skin condition involving mutations in the calcium ATPase pump, with two types: type 1, which follows Blaschko's lines, and type 2, which features increased severity in generalized cases.
  • Type 1 segmental DD is challenging to diagnose due to its late onset, lack of family history, and similar features to other skin conditions like lichen planus and psoriasis.
  • The report documents two cases, highlighting symptoms, dermoscopic findings, histopathological correlations, and effective treatment with tretinoin gel for the first patient.

Background: Limited data on dermatoscopy of nodular/plaque-type T-/B-cell primary cutaneous lymphomas (PCLs) is available.

Objective: To describe dermatoscopic features of nodular/plaque-type PCLs, comparing them with those of clinical mimickers (pseudolymphomas, tumors, and inflammatory lesions) and investigating possible differences according to histologic subtypes.

Methods: Participants were invited to join this retrospective, multicenter case-control study by submitting histologically/immunohistochemically confirmed instances of nodular/plaque-type PCLs and controls.

Dear Editor, A 67-year-old man of Kosovar-Albanian ethnic origin (skin phenotype IV) presented to our dermatology clinic with generalized hyperpigmented patches and plaques all over the body, so-called melanoerythroderma (Figure 1). The lesions, which first appeared nearly six years ago, developed gradually; they were diagnosed as mycosis fungoides (MF), and were subsequently treated only with topical corticosteroids. We performed further examinations upon admission to our department.

Dear Editor,We present the case of a 40-year old male patient with lymphomatoid papulosis of a waxing and waning course on whom three biopsies were performed during a 14-year period with no change in histopathological or immunophenotypical characteristics. Lymphomatoid papulosis (LP) is a chronic, recurrent, self-healing papulonodular skin eruption with the histopathologic features of a cutaneous T-cell lymphoma but an often benign and indolent clinical course (1). It is designated as a primary, cutaneous, CD30+ lymphoproliferative disorder.

Dear Editor, the association between lymphomas and autoimmune manifestations, as well as the prevalence of the cases of coexistent lymphomas and autoimmune conditions, has not been completely established (1-3). Since cutaneous T-cell lymphoma (CTCL) cases are rare, any hypothesis can only be based on case reports or small case series. We present the case of a male patient with folliculotropic mycosis fungoides (FMF) and synchronous autoimmune hepatitis (AIH) with extremely high levels of cancer antigen 19-9 (CA 19-9).

Nodular melanoma is the most aggressive subtype of melanoma, with rapid growth rate and metastatic potential. It is usually diagnosed at a locally advanced stage (Breslow thickness <2 mm) and is therefore associated with a poor prognosis. Nodular melanoma often does not fit the classic clinical ABCD criteria, but rather the EFG rule or 3 Cs criteria.

Syringomas are benign tumors of adnexal origin, and eruptive syringoma is an extremely rare subtype. In this paper, we present a case of a unusual occurrence of eruptive syringoma in 66-year old woman that includes clinical and pathohistological findings and the review of the clinical picture, diagnosis, and treatment options.

Pyoderma gangrenosum is a rare, neutrophilic ulcerative skin disease of unknown etiology often associated with an underlying systemic disease. We present a case of a pyoderma gangrenosum that was initially misdiagnosed and treated as squamous cell carcinoma in another hospital. Multiple surgical treatments triggered postoperative exacerbations and further rapid progression of the lesions.

M. marinum, a nontuberculous mycobacterium, is a rare human pathogen widely distributed in the aquatic environment. In the previous century, epidemics took place due to inadequately chlorinated swimming pool water.

Palisaded neutrophilic granulomatous dermatitis (PNGD) is a rare entity that has been clearly defined neither clinically nor histopathologically. PNGD has been associated with some immune-mediated disorders such as rheumatoid arthritis, systemic lupus erythematosus, systemic vasculitis, Behçet's disease, as well as with lymphoproliferative conditions, bacterial endocarditis, sarcoidosis, and various drugs. We present a 44-year-old Caucasian woman with roundish erythematous-livid plaque and erythematous papules on the left calf that were present for three months.

Primary cutaneous follicle center lymphoma is an indolent primary cutaneous B-cell lymphoma originating from the follicle center cells, composed of a combination of centrocytes (small and large cleaved cells) and centroblasts (large noncleaved cells) with a follicular, follicular/diffuse, or diffuse growth pattern. Lesions are mostly located on the head, neck and trunk. A case is presented of a 56-year-old male patient with primary cutaneous follicle center lymphoma, with lesions involving the skin of the back, shoulders, presternal area and right forearm.

The aim of the study was to investigate the squamous cell carcinoma (SCC) incidence in Croatia in the 2003-2005 period. The cases of SCC were retrospectively studied. Data were collected from University Department of Dermatology and Venereology, Zagreb University Hospital Center and National Cancer Registry.

Pyoderma chronica vegetans is a rare condition clinically characterized by large verrucous plaques with elevated borders and multiple pustules. Although the etiology is unknown, it is generally believed that vegetating reaction is due to an immune system dysfunction or immunosuppressive state. We report on a 72-year-old man with pyoderma chronica of the buttocks.

The histologic picture of intraepidermal and subepidermal autoimmune bullous dermatoses is presented. Histologic changes are described according to the temporal evolution of lesions, with special reference to crucial elements of the histologic differential diagnosis. The diagnosis of autoimmune bullous dermatoses is complex, mostly requiring additional immunofluorescence assays along with histoclinical correlation to detect the antibodies or target antigen by the methods of molecular biology or immunohistochemistry.

Porokeratosis is the common name of several diseases of unknown pathogenesis, which are similar in clinical appearance. It was first described in 1893 and was thought to be a disorder of sweat glands, hence the name porokeratosis. The lesion that can be found in all cases is annular, with atrophic center, and hyperkeratotic outer ring.

This study presents the incidence of major nonmelanoma skin cancers (major NMSCs), other nonmelanoma skin cancers (other NMSCs) and malignant melanoma (MM) in Croatia. The skin cancers recorded between 1 January 2003 and 31 December 2005 were retrospectively analyzed. Until 2003, the incidence of major NMSCs and other NMSCs was not estimated in Croatia.
