The naming journey of alopecia areata: an odyssey in medical history

Alopecia Areata (AA), a condition marked by hair loss in patches, has been identified and described in numerous ways throughout history, highlighting the evolution of our understanding of this complex disorder. This essay aims to explore the journey of how AA got its name, making it more accessible for the general public.

The name “Alopecia Areata” wasn’t coined overnight. It has been christened with a myriad of names over the centuries, each corresponding to the historical period and the level of comprehension of the condition at that time. One of the earliest references to AA was found in the Ebers papyrus, an ancient Egyptian medical document, where it was referred to as “bite alopecia,” capturing the patchy nature of the hair loss.

The term “alopecia” itself was used by the ancient Greek physician Hippocrates. However, it was the Roman medical writer Celsus who described “areas” of alopecia, leading to the condition being referred to as “area Celsi” or “alopecia Celsi” in early literature. This description also gave rise to more colloquial names, such as “fox’s-evil.”

The 17th-century German physician Johannes Jonston furthered our understanding by providing a detailed description of an alopecia patch in his book, “Medicina Practica.” This contribution led to the term “Area Jonstoni,” or Jonston’s alopecia. Still, it wasn’t until French dermatologist François Boissier Sauvages de Lacroix used the term “alopecia areata” in his book “Nosologia Methodica” that the name we use today started to take shape. Despite being coined in 1763, it took a considerable amount of time for it to gain universal acceptance.

Throughout the 19th century, AA was commonly referred to as “porrigo decalvans,” a term derived from Latin words for dandruff and baldness. This period also witnessed some confusion between AA and ringworm, leading to the term “tinea decalvans.” In attempts to attribute AA to an infectious cause, the term “phytoalopecia” was also suggested. Other terms, such as “accidental alopecia,” were also floated around during this time.

As we moved into the 20th century, the term “alopecia areata” started to gain acceptance, as evidenced by the gradual decline of the term “porrigo decalvans.” This shift represented a growing understanding of the condition and the need for a more accurate descriptor.

Interestingly, various subtypes of AA were also given unique names. Terms such as “Cazenave’s vitiligo,” “Celsus’ vitiligo,” “vitiligo capitis,” and “achromatous porrigo” were used to describe conditions where vitiligo, a condition causing skin discoloration, was associated with AA. The term “alopecia ophiasis” was inspired by the original descriptions by Celsus, and “alopecia barbae” was first found in a German-Latin dictionary from 1691, but it took another 175 years before it appeared in print again.

AA’s nomenclature evolved with the development of its understanding, leading to terms like “alopecia universalis,” “alopecia totalis,” and “patchy alopecia areata” emerging in the 18th and 19th centuries, while “alopecia areata diffusa” only surfaced in the mid-20th century.

Interestingly, this journey is not just limited to English vernacular, but spans various languages and cultures. In French medical literature, “la pelade” was a common term until recently, with variations such as “teigne pelade,” “pelade achromateuse,” “pelade ophiasique,” and “pelade décalvante” also used.

In the rich tapestry of Indian Ayurvedic medicine, AA is identified as “Indralupta,” with “Ruhya” being the term for alopecia universalis, illustrating the diversity of names across cultures. Similarly, in early Chinese medical texts, the condition was often referred to as “ghost shaved hair,” a vivid metaphor for the sudden, unexplained hair loss. Presently, Chinese traditional medicine often labels AA as “oily wind,” a term traceable back to the 17th-century book “Surgical Authentic” by Chen Shigong.

This linguistic journey of Alopecia Areata’s naming provides a fascinating insight into the historical evolution of our understanding of the condition. From “bite alopecia” to “porrigo decalvans,” to the various names in different cultures, these terminologies reflect the growth of our knowledge, shaped by a range of influences such as societal beliefs, scientific discoveries, and linguistic nuances.

The name Alopecia Areata, as we know it today, is not just a label for a medical condition. It is a testament to centuries of human curiosity, investigation, and the tireless quest for understanding. As science continues to progress, our comprehension of conditions like AA will undoubtedly evolve, and who knows, perhaps leading to new names that more accurately reflect the intricacies of this enigmatic condition.

In conclusion, the history of Alopecia Areata is more than a tale of a disease. It is a chronicle of our ever-evolving understanding of human health and disease. Every name it has borne is a signpost marking our journey towards unraveling its mysteries. As we move forward, these historical footprints can serve as a reminder of how far we’ve come, and a beacon illuminating our path to future discoveries.
