Overview

Magniffyer, Painting by Shelley EnszNailfold capillaroscopy is the best way to tell if someone has primary or seconday Raynaud's. Capillaries are very tiny blood vessels. Capillaries are very close to the surface of the skin, particularly near the base of fingernails.

For nailfold capillaroscopy, the doctor puts drop of oil at the base of each fingernail and then looks at them under a strong magnifier.

Normal patterns indicate primary Raynaud's. Abnormal patterns indicate an underlying connective tissue disease, such as scleroderma, dermatomyositis, or lupus. (Also see What is Raynaud's?, What is Scleroderma?, Types of Scleroderma and Systemic Symptoms)

State of the art on nailfold capillaroscopy (NFC) in dermatomyositis (DM) and polymyositis (PM). The overview confirms that NFC is a safe and noninvasive tool able to help the clinician in the diagnosis of DM and PM and to better characterize the phase of disease activity of these patients. PubMed, Semin Arthritis Rheum, 06/28/2017. (Also see Dermatomyositis and Polymyositis)

New tools can potentially play key role in early diagnosis of systemic sclerosis. The results of two studies presented today at the Annual European Congress of Rheumatology (EULAR) 2017 press conference highlight the use of two new tools. News Medical, 06/14/2017. (Also see Antibodies)

Nailfold digital capillaroscopic findings in patients with diffuse and limited cutaneous systemic sclerosis (LcSSc). We found no association between the patterns of capillaroscopy and SSc subtypes; early scleroderma pattern of capillaroscopy was significantly associated with early LcSSc, compatible with the slower course of the disease in LcSSc. PubMed, Reumatologia, 2017;55(1):15-23.

Association Between Nailfold Capillaroscopy (NVC) Findings and Pulmonary Function Tests in Patients with Systemic Sclerosis (SSc). Prospective studies are warranted to determine whether NVC is useful for studying pulmonary function in SSc. PubMed, J Rheumatol, 11/15/2014.

Handheld Dermatoscope Works, Too

(PDF) The Handheld Dermatoscope as a Nail-Fold Capillaroscopic Instrument. The unmodified handheld dermatoscope may be used as a capillaroscopic instrument to detect a scleroderma-dermatomyositis pattern and to help the dermatologist in the clinical diagnosis of connective tissue disorders. American Medical Association.

Primary Raynaud's and Nailfold Capillaroscopy

Primary Raynaud's. When Raynaud's appears by itself, without any other medical condition, it is called Primary Raynaud's, or Raynaud's Disease. More than 80% of people with Raynaud's have it by itself, not caused by any serious underlying illness. ISN.

Secondary Raynaud's and Nailfold Capillaroscopy

Secondary Raynaud's. When Raynaud's appears along with autoimmune diseases such as scleroderma, systemic lupus erythematosus, or rheumatoid arthritis, it is called Secondary Raynaud's, or Raynaud's Phenomenon. ISN.

Handheld Dermatoscope photo, copyright Archives of DermatologyThe Handheld Dermatoscope as a Nail-Fold Capillaroscopic Instrument. The presence of nailfold capillary abnormalities may be useful in diagnosing several connective tissue disorders, including scleroderma, dermatomyositis, and mixed connective tissue disease, and in differentiating primary Raynaud phenomenon from Raynaud phenomenon due to scleroderma and mixed connective tissue disease.
