Cutaneous symptoms include localized swellings, angioedema, and pruritus. Diagnosis is by surgical extraction of the adult parasite and confirmation of species by morphology. The disease is endemic to Central and West Africa. [visualdx.com]

Swelling are similar to Calabar swellings due to L. loa nematodes. Calabar swellings are episodic angioedema of the arms and legs due to immune reactions. They are 3–10 cm, non erythematous, and non pitting. [pusware.com]

Adult forms migrate through subcutaneous tissues resulting in intermittent swellings called Calabar swellings, and also migrate beneath the eye conjunctiva (Eye worm). Microfilariae circulate in the bloodstream during the day. [the-travel-doctor.com]

Dermatitis and ocular lesions are commonly associated with the infection and in long standing cases there is blindness, hence the name river blindness for those who are close to rivers in which the vectors are breeding. [cehjournal.org]

Cutaneous symptoms include papular dermatitis, pruritus, lichenification, atrophy, and a "leopard-skin" depigmentation. [visualdx.com]

Common adverse effects were increased pruritus and acute papular dermatitis in 45% of 86 mf carriers on day 6 after treatment. No serious adverse side-effects were noticed in about 700 treated persons. [ncbi.nlm.nih.gov]

Aside from the onchocercoma, the five classic skin eruptions associated with onchocerciasis are as follows: Acute papular onchodermatitis Chronic papular onchodermatitis Lichenified onchodermatitis Skin atrophy Skin depigmentation. [emedicine.medscape.com]

In Latin America, a variety of more acute skin lesions occurs, while chronic skin lesions are less common. [emedicine.medscape.com]

Acute papular onchodermatitis consists of pruritic papules 1-3 mm in diameter that may progress into vesicles or pustules. Chronic papular onchodermatitis consists of flat-topped, hyperpigmented, pruritic papules typically 3-9 mm in diameter. [emedicine.medscape.com]

Skin changes range from papules to lichenification to depigmentation and finally, to “hanging groin” (a pouch of swollen lymph tissue). Eye damage includes corneal injury (sclerosing keratitis), uveitis, and chorioretinitis. [the-travel-doctor.com]
