About cutaneous t-cell lymphoma (ctcl) cutaneous t-cell lymphomas (ctcls) result from a malignant change that occurs in a single t cell located in the skin. These changes cause a normal, healthy t cell to start growing and dividing uncontrollably. These cells accumulate in the skin and show up as skin abnormalities called “skin lesions.
In a phase 2 trial of 48 patients with cd30-positive relapsed or refractory cutaneous t-cell lymphomas, brentuximab vedotin showed notable activity, with 35 (73%) of 48 patients achieving an objective response, 17 (35%) of 48 achieving a complete response, and a median progression-free survival of 1 year.
The clinical entities encompassed by the term cutaneous t-cell lymphomas share several components: the epidermal and/or dermal microenvironment, a clonal t-cell population, and a modulated antitumor response. 23,24 it has to be kept in mind that due to the rare occurrence of ctcls in general and of the less prevalent subtypes in particular.

We hypothesize that cd30+ tumor cells in some ctcl derive from th17 or recently discovered th22 cells. Alternatively, th17/th22 differentiation occurs during tumor progression. Confirmation of this hypothesis could lead to new prognostic markers and cytokine targeted therapies for cd30+ cutaneous t-cell lymphoproliferative disorders.
Cd30-mediated nf-κb activation in cutaneous t-cell lymphoma cells. ( a ) activation of nf-κb pathways (canonical and alternative) is shown by western blot analysis indicating the degradation of iκ-bα (37 kda) at 30 minutes of cd30 stimulation and processing of p100 to p52, at 16 hours of cd30 stimulation of cutaneous anaplastic large-cell.
The primary cutaneous cd30 + lymphoproliferative disorders (lpds) are a group of generally indolent-behaving, primary cutaneous lymphomas that include lymphomatoid papulosis (lyp), primary cutaneous anaplastic large cell lymphoma (pcalcl), and “borderline cases,” a classification that acknowledges overlap between these entities. 1 as a group, the cd30 + lpds account for ∼10% of cutaneous.
Cd30 is promising target as it is universally expressed in virtually all classical hodgkin lymphomas, anaplastic large cell lymphomas, and in a proportion of other lymphoma types, including cutaneous t cell lymphomas and diffuse large b cell lymphomas. Preclinical studies with cd30-directed car-t cells support the feasibility of this approach.

All 12 intravascular large t-cell lesions were intralymphatic; the majority (9) were cd30 + t-cell lymphoproliferative disorders (tlpds), 5 further classified as intravascular alk − alcl. One alk + alcl and 2 benign microscopic intravascular t-cell proliferations were also intralymphatic.
The diagnosis of cutaneous t-cell lymphoma (ctcl) requires accurate histopathology, including immunocytochemistry, as well as careful clinical appraisal and analysis for t-cell clonality. This paper reviews the key histologic features of mycosis fungoides (mf) and its variants, and of lymphomatoid papulosis (lyp). Mycosis fungoides is an epidermotropic ctcl that evolves through distinct.

Primary cutaneous cd30-positive (anaplastic) large t-cell lymphoma and lymphomatoid papulosis have many overlapping clinical, histologic, and immunophenotypic features.
One of the most common forms of t-cell lymphoma is cutaneous t-cell lymphoma (ctcl), a general term for t-cell lymphomas that involve the skin. Ctcl can also involve the blood, lymph nodes, and other internal organs. Symptoms can include dry skin, itching (which can be severe), a red rash, and enlarged lymph nodes.
Primary cutaneous cd30 + lcl typically occurs in adults presenting with solitary or localized (ulcerating) nodules or tumors (fig.
