"Sign in a local hospital: 'From all of us here…

“Xmas” (Christmas) shouldn’t be confused with “eczemas” (a skin disease), but there are jokes. Merry Eczema (1992) by David Shrigley was a book title.

“To all dry skin sufferers - a merry Eczemas! #greetings #pbd” was posted on Twitter by “Light The Lamp Not The Rat” on December 23, 2009. “To everyone suffering from dry, flakey and itchy skin this festive period, i wish you a Merry Eczemas” was posted on Twitter by Darrell Parsons on December 3, 2010.

“Sign in my local hospital; ‘From all of us here at the Dermotology Department .Merry Eczemas’” was posted on Twitter by 🤣 The Dad Joke Man 😉 on December 23, 2017.

Wikipedia: Xmas
Xmas (also X-mas) is a common abbreviation of the word Christmas. It is sometimes pronounced /ˈɛksməs/, but Xmas, and variants such as Xtemass, originated as handwriting abbreviations for the typical pronunciation /ˈkrɪsməs/. The “X” comes from the Greek letter Chi, which is the first letter of the Greek word Christós (Χριστός), which became Christ in English. The suffix -mas is from the Latin-derived Old English word for Mass.

Wikipedia: Dermatitis
Dermatitis, also known as eczema, is a group of diseases that result in inflammation of the skin. These diseases are characterized by itchiness, red skin and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to the entire body.
