Lymphocytoma cutis following excision arthroplasty.

Cutaneous pseudolymphomas are a group of benign reactive T or B cell lymphoproliferative processes of diverse etiology that simulate cutaneous lymphomas clinically and histologically. We report one such case of pseudolymphoma occurring in the groin of an elderly lady with a history of excision arthroplasty and cementing done at the same site decades ago.

Nonablative lasers and nonlaser systems in dermatology: current status.

Unlabelled: Nonablative lasers and nonlaser systems are newer systems used for skin rejuvenation, tightening, body sculpting, and scar remodeling.

Devices: Different technologies such as lasers, Intense Pulsed Light (IPL), and radiofrequency have been introduced. Most nonablative laser systems emit light within the infrared portion of the electromagnetic spectrum (1000-1500 nm).

Facial granulomas secondary to injection of semi-permanent cosmetic dermal filler containing acrylic hydrogel particles.

Various reports of long-term complications with semi-permanent fillers, appearing several years after injections have created some concern about their long-term safety profile. We report a case of foreign body granuloma secondary to dermal filler containing a copolymer of the acrylic hydrogel particles, hydroxyethylmethacrylate and ethylmethacrylate, occurring 2 years after the injection. The foreign body granulomas could not be treated satisfactorily with intralesional steroids, and the patient required a surgical excision of her granulomas.
