    Abstract Galli-Galli disease (GGD) is a rare genodermatosis that exhibits autosomal dominant inheritance with variable penetrance. GGD typically manifests with erythematous macules, papules, and reticulate hyperpigmentation in flexural areas. A distinct atypical variant exists, which features brown macules predominantly on the trunk, lower limbs, and extremities, with a notable absence of the hallmark reticulated hyperpigmentation in flexural areas. This review includes a detailed literature search and examines cases since GGD's first description in 1982. It aims to synthesize the current knowledge on GGD, covering its etiology, clinical presentation, histopathology, diagnosis, and treatment. A significant aspect of this review is the exploration of the genetic, histopathological, and clinical parallels between GGD and Dowling-Degos disease (DDD), which is another rare autosomal dominant genodermatosis, particularly focusing on their shared mutations in the

    Abstract Primary cutaneous γδ T-cell lymphomas (PCGDTLs) are a heterogeneous group of lymphomas representing about 1% of primary cutaneous T-cell lymphomas (CTCLs) and mostly regarded as clinically aggressive. Current WHO-EORTC classification recognizes different clinic-pathologic subsets of PCGDTL, but it suggests that cases showing a mycosis fungoides (MF)-like clinical presentation and histopathology should be classified as MF irrespective of phenotype for their indolent course. Herein, we describe a case of γδ-MF, featuring at onset a granulomatous pattern, with subsequent clinical worsening signaled by the development of an ulcero-necrotic lesion and systemic dissemination, leading to death in 5 months. Clinical progression was sustained by a shift to mature T-cell lymphoma composed of medium to large-sized blastoid T-cells featuring a T-cell receptor (TCR) silent immunophenotype.

    Abstract The World Health Organization (WHO) classification of hematopoietic and lymphoid tumors identifies distinctive subtypes of peripheral T-cell lymphoma (PTCL), and, additionally, some PTCLs involving mostly extranodal sites like the skin. The difficulty of classifying PTCLs according to the normal stages of T-cell differentiation and the lack of definitive diagnostic markers for most of the subtypes make the diagnosis of these diseases challenging. PTCL cases which do not fit into any of the specifically defined entities are categorized as PTCL not otherwise specified (PTCL-NOS). PTCLs-NOS represent less than 2% of the total cases of T-cell lymphoma involving the skin. This article illustrates a case of a PTCL-NOS in which tumor cells have an activated cytotoxic TCRαβ+CD3+CD4+CD56+ T-cell phenotype and histopathologic features of subcutaneous panniculitis-like T-cell lymphoma, leading to a fatal outcome.

    Abstract Intravascular large B-cell lymphoma (IVLBCL) is one of the rarest B-cell non-Hodgkin lymphomas (NHL), with an aggressive clinical behavior and a poor prognosis; in fact, its treatment is still an unmet clinical need, with a 3-year overall survival (OS) rate of 60% to 81%, and a central nervous system relapse rate of 25%. It usually presents as a widespread disease at diagnosis, with multi-organ involvement. Previously considered as a diffuse large B-cell lymphoma variant, it now represents a different extranodal large B-cell lymphoma entity in the last WHO Classification of tumors of hematopoietic and lymphoid tissues. We hereby describe the case of an 84-year-old Italian woman with an IVLBCL, cutaneous variant, who suffered from early relapse after R-COMP chemotherapy regimen, and was therefore treated with a palliative metronomic chemotherapy. Interestingly, neoplastic cells showed CD30 expression at relapse. CD30 positivity has never been reported in this disease so far, and its expression is known to be involved in NF-kB activation. CD30 expression may be further studied as for prognostic and therapeutic significance; in fact, new therapeutic strategies, such as antibody-drug conjugate targeting CD30, are now available.

    Abstract Pagetoid reticulosis (PR) is a low-grade primary cutaneous T-cell lymphoma showing localized patches or plaques with an intrapeidermal proliferation of neoplastic T-cells with heterogeneous immunophenotype. We describe a 73-year-old woman with a 8-year history of gluteal lesions of PR, whom large blast cells were CD4/CD8 double negative T-cells with an activated cytotoxic profile. The case was investigated using a broad panel of monoclonal antibodies including TCRγM1, a new available antibody that recognizes the γ chain subunit of the T-cell receptor (TCR) in formalin-fixed paraffin-embedded tissue. Large blast cells were simultaneously positive for TCRαβ and TCRγδ with an activated cytotoxic phenotype. It is worldwide accepted the mutual exclusive expression of TCRαβ and TCRγδ but six different studies, dealing with TCRγδ expression in various types of extra-nodal lymphomas, reported cases whom tumor cells expressed simultaneously TCRαβ and TCRγδ. Our data and those of similar reports, suggest the possibility of existence of a subset of extra-nodal T-cell lymphomas showing simultaneous expression by tumor cells of TCRγδ and TCRαβ with an immunoprofile consistent with an origin from TCRγδ+ T lymphocytes. This unusual subset has preferential, but not exclusive, skin localization and variable epidermotropism.

    Abstract Castleman's disease (CD) is an unusual lymphoid hyperplasia occurring in the mediastinal lymph nodes and, less frequently, in the neck lymph nodes. CD is classified clinically into a unicentric and a multicentric type, whereas three histomorphological variants are recognized: the hyaline vascular type, the intermediate type and the plasma cell type. We report the clinical and pathological features of a 54-year-old female suffering with multiple sclerosis and developing a lymph node hyaline-vascular type CD relapsing in the skin after 24 months. Histological features showed a nodular dermatitis with atrophic germinal centers and an 'onion skin' rimming of lymphocytes in the mantle zone with numerous mantle zone lymphocytes with clear cytoplasm, with a CD20+, CD79a+, IgM+, IgG-, IgA-, CD5-, CD10-, CD43-, CD45RO-, bcl-2+ and bcl-6- phenotype with polytypic nature supporting the diagnosis of lymphoid variant of hyaline-vascular CD. This case shows that skin CD recapitulates all the histological variants of lymph node CD. Considering the many similarities between the present case and the primary cutaneous marginal zone lymphoma, it is important to bear in mind this atypical lymphoproliferative disorder in order to avoid overdiagnosis and overtreatment.

    Abstract CD4/CD8 double negative mycosis fungoides (MF) is a rare phenotypic variant of this epidermotropic cutaneous T-cell lymphoma. Clinically, this MF form manifests with unusual appearances such as annular lesions confined to one body region as in our patient in whom the lesions were found on the left lower leg. The cellular origin of CD4/CD8 double negative MF is unknown. In our case, the intraepidermal CD4/CD8 double negative clonal T-lymphocytes (CD2+, CD4-, CD8-, CD30-, beta-F1+) expressed programmed death-1 but were negative for CXCL-13 and cytotoxic molecules (TIA-1, granzyme B, perforin). Our observation may give an insight into the histogenesis of this unique MF variant and may also be of therapeutic significance because programmed death-1 may serve as a target for therapeutic intervention.
