Cutaneous manifestations of drug reactions are common yet vary widely in their appearance and degree of internal organ involvement. Serum sickness--like reactions, symmetrical drug-related intertriginous and flexural exanthem, granulomatous drug eruption, pseudolymphoma, and drug-induced lupus are medication-induced conditions with dermatologic presentations. Many of the conditions discussed are relatively rare but nonetheless demand our attention and understanding.

Helicobacter pylori is a Gram-negative bacterium identified for the first time about 30 years ago and commonly considered as the main pathogenic factor of gastritis and peptic ulcer. Since then, it was found to be associated with several gastrointestinal and extra-gastrointestinal diseases. Helicobacter pylori is also associated with many skin disorders including, but not limited to, chronic urticaria, rosacea, lichen planus, atopic dermatitis, psoriasis, pemphigus vulgaris, vitiligo, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, primary cutaneous marginal zone B-cell lymphomas and cutaneous T-cell pseudolymphoma.

Cutaneous pseudolymphoma (CPL) refers to a group of benign, reactive processes that mimic cutaneous lymphoma and are associated with a variety of triggering immune stimuli, including arthropod bites, drugs, and foreign bodies. In children, most cases of CPL are due to a variant of Borreliosis that is specific to Eurasia. Cutaneous pseudolymphoma secondary to ear piercing has only been documented in adults.

In the last 30 years, there has been a strong interest in vascular proliferations. Pyogenic granuloma was not only renamed lobular capillary hemangioma, but also the conceptual interpretation was also changed from an overgrowth of granulation tissue to a genuine hemangioma (or benign vascular neoplasm). We describe 19 cases of patients who presented clinically with a vascular lesion, characteristically a pyogenic granuloma or lobular hemangioma, where the histopathological findings led to the pathologic concern for a lymphoma of the skin.

Cutaneous pseudolymphoma (CPL) encompasses various forms of benign lymphocytic proliferative dermatoses that mimic the clinical and/or pathological changes of lymphoma. The clinical manifestations of CPL vary due to differences in the pathogenesis, and accordingly, no specific treatment has been identified. Here, we report a case of CPL on the nose, which had a distinctive appearance and was treated successfully using a combination of intralesional interferon alpha-1b and compound betamethasone (betamethasone sodium phosphate and betamethasone dipropionate).

We report an unusual case of drug-associated granulomatous CD30 T-cell pseudolymphoma secondary to amlodipine. A 55-year-old Chinese man presented with a 6-month eruption of disseminated erythematous dermal papulonodules and annular infiltrated plaques over his neck and limbs symmetrically. Histopathology revealed a perivascular and interstitial infiltrate of histiocytes, eosinophils and morphologically normal lymphocytes associated with CD30 expression.

Combination therapy with ipilimumab and nivolumab is an adjuvant treatment approach for metastatic melanoma that boasts increased 3-year survival when compared with a single immunotherapy agent. Combination therapy, however, is associated with increased toxicities, especially cutaneous side-effects. Here we present a patient with metastatic melanoma and a sudden eruption of painful nodules on the face and arms 10 days after the administration of the fourth dose of combination ipilimumab/nivolumab.
