Rash after visiting Tucson.
Cactus dermatitis is a common problem among harvesters of cactus fruit. The smaller spines (glochidia) are responsible for most of the dermatitis. Easily separated from the body of the plant, the glochidia may be transferred to bystanders through contact with clothing or pets exposed to these cacti. Removal of the glochidia from the skin is key to treatment, and household glue may aid in this extraction.

Targetoid hemosiderotic hemangioma- a dynamic vascular tumor: report of 3 cases with episodic and cyclic changes and comparison with solitary angiokeratomas.
BACKGROUND: Both targetoid hemosiderotic hemangiomas (THH) and solitary angiokeratomas (SAK) are acquired vascular malformations formed by superficial vascular ectasias possibly caused by trauma. OBJECTIVE: We compare the clinicopathologic findings of THHs with those of SAKs and report the clinicopathologic findings of 3 singular cases of THH affected by cyclic or episodic morphologic changes. METHODS: We performed a clinicopathologic study on 33 cases of THH and compared this group with 20 cases of SAK. On selected cases, histochemical and immunohistochemical analyses were evaluated. RESULTS: Overlap of all the clinical and pathologic features studied were identified for THH and SAK. Clinically, they both commonly exhibited a brown or black papule located over the lower extremities that mimicked a melanocytic lesion. Histologically, they both had ectatic papillary dermal vessels with overlying epidermal hyperplasia, and adjacent hemosiderin deposits, extravasated red blood cells, lymphocytic infiltrate, and lymphangiectases. Compared with SAKs, THHs were significantly larger (5.3 vs 3.2 mm), more often excised (elliptical excision) than shave or punch biopsied, and had deeper dermal vessel alterations, more frequent dissecting vascular spaces, and more extensive hemosiderin deposits (all P < .01). THHs presenting with episodic changes were significantly larger than those without (11 vs 4.4 mm, P =.001). CONCLUSION: THHs and SAKs differ in degree, not in type, of clinicopathologic characteristics. This finding suggests that THHs are larger variants of SAKs whose size is the cause of more extensive, prolonged, or recurrent vessel damage. The histologic findings of extravasated red blood cells, hemosiderin, telangiectases, lymphangiectases, and fibrosis implicate trauma in the cause of these acquired vascular malformations.

Dermatologic care behind bars.
Providing dermatologic care in a prison setting is a challenge to the practitioner's ingenuity and patience because of cumbersome methods of transporting prisoners, poor compliance with prescribed regimens, and follow-up care that is not only inadequate but almost nonexistent. Certain prevalent infections such as tinea pedis and condyloma acuminatum probably are specifically induced by the prison environment. Alopecia areata is unexpectedly common and apparently associated with stress. Pruritus, which is common, is related to both environment and stress. Dermatologic diseases seen commonly in blacks are more prevalent because of the population demographics, yet pseudofolliculitis barbae is unusual as a complaint. In this article we review our experiences in establishing a first in-prison dermatology clinic.
