Enhanced cutaneous lymphatic network in the forearms of women with postmastectomy oedema.

Postmastectomy oedema (PMO) of the arm is a common aftermath of axillary lymphatic damage during treatment for breast cancer. The aim of the present study was to quantify the forearm dermal lymphatic capillaries in order to determine whether they exhibit adaptive responses to PMO. Both forearms were examined by fluorescence microlymphography in 16 patients with oedema following treatment for breast cancer (mean swelling 25 +/- 4%) and 19 patients treated for breast cancer but without oedema. Delineated lymphatic networks were analysed stereologically. The main findings were: (1) lymphatic density at any specified distance from the injection site was greater in the swollen arm than the control arm (p < 0.01, t test); (2) taking into account the increased skin area, the total length of lymphatic capillaries in a 1-cm annulus of skin was 676 +/- 56 cm (swollen), compared with 385 +/- 30 cm (control) (p < 0.001, t test); (3) fluorescent marker was transported over a greater distance before draining deep in the swollen arm (2.74 +/- 0.33 cm) than in the control arm (1.59 +/- 0.24 cm) (p = 0.02); (4) there was no evidence of lymphatic dilatation in the swollen arm, and (5) in breast cancer patients without swelling, the arm on the side of radiotherapy/surgery (otherwise referred to as the unswollen arm) showed none of the above changes, indicating that the changes are linked to the oedema rather than being universal responses to breast cancer or its treatment. It is concluded that microlymphatic changes occur in the swollen arm, namely a local superficial rerouting of lymph drainage and either lymphangiogenesis and/or increased recruitment of dormant lymphatic vessels. Since blood capillary angiogenesis occurs in the swollen arms, and lymphangiogenesis occurs in experimental lymphoedema, there is a precedent for proposing lymphangiogenesis in PMO. An increased number of functional vessels would help to maintain the ratio of local tissue drainage capacity to filtration capacity.

Sarcoidosis manifesting as uveitis and menometrorrhagia.

PURPOSE: To report a rare systemic manifestation of sarcoidosis identified in a 47-year-old white woman while she was undergoing evaluation for bilateral recurrent uveitis. METHODS: The patient underwent clinical and laboratory evaluation for bilateral recurrent uveitis including serologic and radiologic testing, a gallium scan, and an endometrial biopsy. RESULTS: Although the serologic tests and chest x-ray were normal, the gallium scan was consistent with sarcoidosis, and the endometrial biopsy provided a tissue diagnosis. CONCLUSION: Sarcoidosis involving the female reproductive tract is rare. A thorough review of systems is crucial in the evaluation of any patient with recurrent uveitis.

Bilateral orbital infiltration as the initial sign of a peripheral T-cell lymphoma presenting in a leukemic phase.

We describe the clinical course of a young woman with a peripheral T-cell lymphoma who presented in a leukemic phase of the disease with an initial complaint of bilateral conjunctival swelling.
